 The Environmental Data Service (EDS) archives and disseminates a broad spectrum of environmental data 
 gathered by the various comoonents of NOAA and by the various cooperating agencies and activities 
 throughout the world. The EDS is a "bank" of worldwide environmental data upon which the researcher may 
 draw to study and analyze environmental phenomena and their impact unon commerce, agriculture, industry, 
 aviation, and other activities of man. The EDS also conducts studies to put environmental phenomena and 
 relations into proper historical and statistical perspective and to provide a basis for assessing 
 changes in the natural environment brought about by man's activities. 
 
 The EDS series of NOAA Technical Reports is a continuation of the former series, the Environmental

 ABSTRACT 
 
 This report describes the rawinsonde data collected during 
 the International Field Year for the Great Lakes (IFYGL), 
 a joint United States-Canadian program conducted in 1972-73 
 for the study of Lake Ontario and its basin. Procedures 
 used in data processing are described, and an inventory of 
 the archived data is given. 
 
 1. INTRODUCTION 
 
 Intensive field operations were conducted from April 1, 1972, through 
 March 31, 1973, in support of the International Field Year for the Great Lakes 
 (IFYGL), a joint United States-Canadian research program aimed at a better 
 understanding of the physical, chemical, and biological processes in and above 
 Lake Ontario and its basin. Some systems operated continuously throughout the 
 Field Year, while others were used during intermittent, intensive observation 
 periods. For the IFYGL rawinsonde observations, the fall was selected as the 
 season with greatest evaporation from the lake, a process to be measured as 
 an atmospheric water balance residual. 
 
 Shortly before the field data collection phase, the responsibility of pro- 
 cessing the rawinsonde data was given to the Center for Experiment Design and 
 Data Analysis (CEDDA) , Environmental Data Service, National Oceanic and Atmos- 
 pheric Administration. Background information on the rawinsonde system and 
 its operation is given in IFYGL Technical Manual No. 6 (Callahan et al., 1976). 
 
 This report contains a description of the methods used in the data 
 processing and an inventory of the final data set, which is available from 
 the IFYGL Archive. Requests for data should be addressed to:

2. DATA ACQUISITION SYSTEM 
 
 A network of six rawinsonde stations, three in the United States and 
 three in Canada, was established around Lake Ontario for IFYGL. Station lo- 
 cations and elevations above mean sea level are shown in figure 1. Releases 
 were scheduled from September 21 to December 10, 1972. As shown in table 1, 
 flights were launched every 3 hr from September 22 to 26, October 2 to 18, 
 October 30 to November 14, and November 21 to December 9. During the re- 
 maining time periods, soundings were made only twice a. day. 
 
 The LORAN-C LO-CATE II Navaid Integrated Upper Air System Model 
 WL-2D(M), developed and manufactured by Beukers Laboratories, Inc., and the 
 compatible radiosonde AUTOMET Model 1223-100, built by the VIZ Manufacturing 
 Co. , were used during IFYGL. This is a complete all-weather upper air wind- 
 finding and meteorological sounding system that collects, transmits, process- 
 es, displays, and records data on magnetic tape and strip charts. No radars, 
 stable platforms, or dish antennas are required. LO-CATE is based on the 
 retransmission concept developed by Beukers Laboratories to determine the 
 position and velocity of remote objects. A balloon-borne radiosonde reports 
 its position to a base station by receiving and retransmitting navigation aid 
 (Navaid) signals via a 403-MHz UHF telemetry link (fig. 2). Transmitting 
 stations were located at Cape Fear, North Carolina (master); Dana, Indiana 
 (slave "A"); and Nantucket, Massachusetts (slave "B").

2.1 Meteorological Data 
 
 Meteorological data were conveyed by frequency modulation of the 
 403-MHz transmitted carrier frequency of the radiosonde. The modulation fre- 
 quency varied from 50 to 2,100 Hz as a function of the parameters being sensed. 
 The transmitter power was about 300 mW. Specially selected carbon hygristors 
 and ceramic rod thermistors measured humidity and temperature respectively. 
 Pressure was obtained from an aneroid cell that drove a pen-arm contact over 
 a strip on which 180 contacts were printed, each representing a discrete 
 pressure. Each contact placed one of three resistors in the modulator circuit 
 in a fixed pattern so that each contact could be identified in the data out- 
 put. The pattern was such that recovery was possible in the event the data 
 stream was temporarily interrupted. Intermediate pressures between the be- 
 ginning edge of adjacent contacts could be determined by interpolation in the 
 data reduction process. 
 
 A meteorological data cycle was completed every 0.8 s. Approximately 
 0.2 s each was spent on temperature, humidity, pressure, and a reference near 
 2,000 Hz produced by a fixed resistor. Between contacts, a midscale refer- 
 ence frequency, near 1,000 Hz, was produced by a precision resistor. 
 
 Switching among the four signals was done by a solid-state commutator. 
 The known sequence of parameters, and the time-based switching of these param- 
 eters, made the meteorological data output suited to fully automatic data 
 processing. This is in contrast to the conventional United States radiosonde, 
 in which the pressure contacts are used for switching the other parameters. 
 
 On the ground, the 403-MHz receiver extracted the meteorological data 
 (50 to 2,100 Hz) and sent them to a meteorological data converter. A meteoro- 
 logical data synchronizer phase-locked an internal segment generator to the 
 high-reference signal telemetered from the sonde. This synchronization 
 allowed timing, decoding, and digitizing of the meteorological elements by 
 the use of a 10-MHz clock. Each time a new parameter was sensed on the ground, 
 the data were digitized and an output was signalled to the central processor, 
 which then converted the data into a format compatible with the magnetic tape 
 recorder. The central processor also drove a strip-chart recorder, which 
 recorded the data in analog form. 
 
 2.2 Wind Data 
 
 At the sonde, the LORAN-C signals were captured by an antenna and min- 
 iature receiver that modulated the 403-MHz carrier at the 100-kHz LORAN-C 
 frequency. The ground 403-MHz receiver extracted the LORAN-C data, and for- 
 warded them to the LO-CATE processor. The processor produced two output 
 signals, each representing the time difference between the signals from two 
 LORAN-C transmitters. The two sets of time differences, expressed in terms 
 of tenths of microseconds, were recorded on an analog strip-chart recorder 
 and were also sent in digital form to the central processor, which put them 
 into a format suitable for recording on the magnetic tape recorder. 
 
The time differences between the signals received from a pair of the 
 LORAN-C transmitters placed the sonde on a hyperbolic line-of-position (LOP) . 
 The intersection of two LOP's, one from each of the two pairs of signals, 
 established sonde position, with change in position from second to second 
 being a measure of the wind at the level of the sonde. 
 
 The accuracy of LORAN-C wind data depends on both the spacing and the 
 crossing angles of the LOP's established by the pairs of transmitting sta- 
 tions. The combination of LORAN-C stations in North Carolina, Massachusetts, 
 and Indiana resulted in close to optimum geometry in the Lake Ontario area. 
 Since winds were derived from changes in position, rather than absolute posi- 
 tions, propagation anomalies tended to cancel out. 
 
 2.3 Recording Methods 
 
 Four methods were used in recording data in the IFYGL rawinsonde net- 
 work. The primary mode was a digital magnetic tape recorder, seven-track IBM 
 compatible, on which data were recorded in raw digital form for later process- 
 ing. The recorded data consisted of time, frequency count of each meteorolog- 
 ical parameter and reference each 0.8 s, and time differences for each of two 
 pairs of LORAN-C signals each second. 
 
 Two analog strip-chart recorders were used as backup. One was dual-pen 
 and displayed two traces, one representing the time-of-arrival difference be- 
 tween one pair of LORAN-C stations, and the other the same information for the 
 other pair. Its main purpose was to provide a real-time monitor of the quali- 
 ty of the data. The second strip-chart recorder provided a record of the 
 meteorological data — much like that obtained by the conventional radiosonde 
 recorder. Because of the fast commutation rate, however, only samples of the 
 meteorological data were recorded, since the pen drive could not react fast 
 enough to catch each 0.2-s transmission period. This recorder, also, served 
 mainly as quality monitor. 
 
 The fourth recording device was an input-output teletype. Before each 
 flight, surface readings, actual time, flight number, serial number, and sen- 
 sor lot numbers were entered through the keyboard and written out onto the 
 magnetic tape as a flight header. A second flight header consisted of baro- 
 switch calibration information (pressure for each contact) entered onto the 
 magnetic tape from punched paper tape provided by the VIZ Manufacturing Co. 
 During each minute of the flight, the teletype printed out 1-min averaged 
 winds and range and bearing from the ground station to the radiosonde. 
 
 3. DATA PROCESSING 
 
 The procedures used at the Center for Experiment Design and Data Analy- 
 sis in processing the IFYGL rawinsonde data are illustrated in figure 3. The 
 original 267 tapes were first dumped, copied, and checked for readability and 
 completeness. The copied tapes were then run through the TRANS program for 
 unpacking and translating the data to CDC-6600 binary words and for time 
 assignment and correlation of the meteorological and LORAN-C data. The out- 
 put consisted of 66 tapes, each containing 48 soundings. These tapes were

run through the PLTRAW program, which produced time-series plots on 35-mm 
 microfilm of the unedited data. This completed the first stage of processing. 
 
 In the second stage, the time-series plots were analyzed, and a study 
 was made of the manual corrections needed for missing or abnormally noisy data. 
 The EDIT program was written to carry out both automated and manual corrections 
 The output consisted of 5-s averages of edited data, which were then passed 
 through the COMPUT program, which converted the meteorological data to tem- 
 perature, specific humidity, and pressure values, and the LORAN-C time differ- 
 ences to values of wind speed and direction. Pseudoadiabatic plots on 35-mm 
 microfilm were also prepared from these data. All programs were written in 
 FORTRAN for NOAA's CDC-6600 computer in Suitland, Maryland. 
 
 3.1 First-Stage Processing 
 
 The COPY program was written primarily to generate backup for the origi- 
 nal tapes. It was also used to position end-of-file marks properly, and to 
 remove abnormally large gaps in the data as well as completely unreadable 
 records. The tapes were copied as soon as received to provide feedback on 
 the information contained to the field stations. The emphasis at this point 
 was readability and completeness of the data. The TRANS program was then 
 used for unpacking the data for parameter and cycle identification, and for 
 time correlation of the meteorological and LORAN-C data. 
 
 The data on the field tapes were a mixture of modified ASCII format and 
 binary data. After these had been converted to CDC-6600 binary words, the 
 parameters had to be identified. The LORAN-C data, recorded every second, 
 were easily distinguishable from the meteorological data because of their 
 large values. The meteorological data were recorded every 0.8 s in the fre- 
 quency range of 50 to 2,100 Hz. The beginning of a meteorological cycle was 
 identified by a reference frequency value of 2,000 ± 100 Hz. The three mete- 
 orological values following a reference frequency were stored as pressure, 
 temperature, and humidity, except in three cases: 
 
 (1) If one of the next three values could be identified as a new 
 reference, the remaining cycle was indicated as missing, and a new cycle was 
 begun. 
 
 (2) If less than four meteorological data values were found between 
 two LORAN-C signals, the remaining cycle was indicated as missing (since the 
 meteorological commutator sends no less than four nor more than six meteoro- 
 logical values per second), and a search for a new reference was begun. 
 
 (3) If six values were found and no reference was identified, a cycle 
 with missing data was stored, and a search for a new reference was begun. 
 
 The time assigned to each meteorological data cycle was derived from 
 computer clock time, which was recorded at the beginning of each data record. 
 The time interval of approximately 16 s between one record and the next was 
 divided into equal increments, corresponding to the number of data cycles in 
 the record. Based on these increments, the times were computed for the suc- 
 cessive data cycles in the record. 
 
10 
 
 The LORAN-C time-delay values were interspersed at 1-s intervals among 
 the meteorological data, with time-delay values from slave A (TDA) and slave B 
 (TDB) appearing at alternating seconds. Since no data were missing and the 
 two sets of values were easily distinguishable, they were stored in two arrays, 
 one representing data at even number and the other at odd number of seconds 
 after rawinsonde release. Times assigned to these data were integral seconds, 
 beginning with the first integral second on or after the time of the record. 
 At the end of each record a check was made to ensure that: 
 
 (1) The number of TDA values did not differ by more than one from the 
 number of TDB values. 
 
 (2) The total number of LORAN-C values received in a record did not 
 differ by more than one from the number of seconds making up the record. 
 
 (3) The total number of LORAN-C values after rawinsonde release did 
 not differ by more than one from the total number of seconds after release. 
 
 No discrepancies of more than 2 s were found, and no corrections were 
 made. 
 
 The PLTRAW program was used for displaying the output from the TRANS 
 program in time-series plots on 35-mm microfilm, still in the form of fre- 
 quencies for the meteorological data (fig. 4) and in time differences for the 
 LORAN-C data. The flight header and baroswitch calibration information was 
 listed before each sounding ,and any that failed range or internal consistency 
 tests were flagged. This film was used for determining manual correction and 
 insertions needed, and is the best display of the quality of the original data. 
 
 3.2 Second-Stage Processing 
 
 The EDIT program was used for pressure contact recognition and auto- 
 mated editing of the data. Manual input to the program was provided as neces- 
 sary. 
 
 3.2.1 Automated Editing 
 
 The first step in the editing program was to convert the contact pres- 
 sure pattern to actual contact numbers. The pattern recognition routine was 
 based on value changes every 5th and 15th contact. The surface pressure was 
 used for determining the first contact after rawinsonde release. If the first 
 10 contacts did not fit this pattern, it was assumed that the surface reading 
 was inaccurate, and a contact number one higher was used as the initial con- 
 tact. If, again, the pattern could not be established, one contact lower than 
 the surface contact was used as the starting point. If this failed, the flight 
 was examined, and a contact correction was entered manually or the sounding 
 was deleted. If, after the initial contact pattern had been established, the 
 recognition routine failed, the program would insert one contact on the assump- 
 tion that it had been missed because of noisy data. If the routine still con- 
 tinued to fail to recognize the pattern, the sounding was terminated and the 
 time-series plots of the data were examined to assess if additional data could 
 be salvaged from the sounding.

 Once the highest contact had been established, a three-pass editing 
 scheme was used in processing the high-reference (2,000 Hz), midreference 
 (1,000 Hz, recorded when the baroswitch was "off contact"), temperature, hu- 
 midity, and LORAN-C values. 
 
 In the first pass, a gross range test was applied to the values, and 
 missing-data indicators were inserted for points that were obviously erroneous. 
 If data gaps extended beyond the least-squares fit used in the second pass 
 (see below), they were filled through linear interpolation. These interpolated 
 values are indicated by flags in the final archive product. 
 
 In the second pass, a second-degree least-squares fit was applied to the 
 data by means of a routine developed by Acheson (1975). For high reference and 
 midreference, 64 points were fitted at a time. Point values less than 2.5 times 
 the standard deviation from the curve were accepted. Discarded values (in- 
 cluding those discarded in the first pass) were replaced by values from the 
 curve. Humidity and temperature were edited by fitting 32 points at a time 
 and using 3 and 2.5 times the standard deviation respectively. On all parameters, 
 a 50-percent overlap was used for successive least-squares fits, i.e., if 64 
 points were to be fitted, points 1 to 64 were used, followed by 32 to 96, 64 
 to 128, and so on. 
 
 For LORAN-C time differences, 100 points were used at a time in the 
 least-squares fit, with 3.0 times the standard deviation used as the acceptance 
 criterion. Lane jumps — a multiple of 10 ys change in the data — occurred, and 
 a special routine was written to remove them between the first and second pass 
 of the EDIT program. All missing data were replaced by extrapolation, instead 
 of interpolation, in case a lane jump occurred where data were missing. 
 
 The third pass consisted of routines that reduced the data to 5-s aver- 
 ages. The averages of the metorological data were formed from the 0.8-s values 
 within a 5-s interval. Of the two LORAN-C time differences, one set (TDA) 
 came in on odd seconds after rawinsonde release, i.e., 1, 3, 5, 7, etc., while 
 the other (TDB) came in on even seconds, i.e., 2, 4, 6, 8, etc. The 5-s aver- 
 ages were therefore formed by alternating averaging of two and three values. 
 The first pair was formed by the values at seconds 1 and 2; the pair at second 
 5 was formed by the average of TDA values at seconds 3, 5, and 7, and the 
 average of TDB values at seconds 4 and 6; and the pair at 10 s was formed from 
 averaged TDB values at seconds 8, 10, and 12, and TDA values at seconds 9 and 11. 
 
 3.2.2 Manual Corrections 
 
 Manual corrections were made in a manner that allowed maximum flexibil- 
 ity in deleting and inserting data in order that the data could be processed 
 as much as possible by the automated procedure described in the preceding 
 section. Based on review of the time-series microfilm plots of the original 
 data, the following actions were often necessary: 
 
 (1) Some flights were deleted. This was done when a sounding was 
 aborted and when the baseline information had been recorded although no 
 sounding had been made. 
 
13 
 
 (2) If the signal had degenerated before the end of a sounding, the 
 time and contact of balloon burst or of the last good data point were identi- 
 fied to aid the contact pattern routine in not reading beyond the end of good 
 data. 
 
 (3) In the case of very noisy data or of interference from another 
 sonde, any parameter of a given flight was deleted for a period of up to 
 
 100 s. Such deletions were treated in the automated editing as missing data. 
 
 (4) Values were strategically inserted into the pressure contact 
 pattern when the data were too noisy to be recognized by the pattern recog- 
 nition routine. 
 
 (5) Inaccuracies in the flight header information, which had been 
 flagged on the microfilm plots, were corrected by review of log books and 
 of information pertaining to other flights. 
 
 (6) An entire flight header, an entire baroswitch record, or all 
 meteorological or LORAN-C data, or any combination of these, were inserted 
 when a substantial part or all the data for sounding were either missing or 
 could not be read off the tape. The data for the flight header were ob- 
 tained from forms filled out in the field. The baroswitch calibration 
 information was obtained from a listing supplied by the manufacturer for 
 each sonde. The meteorological and LORAN-C data were extracted from strip 
 charts. The meteorological data had been recorded in the field in ordi- 
 nate values of 0.0 to 10.0. Based on these strip charts, temperature, 
 humidity, and midreference were coded every contact. These data were 
 punched on cards, merged with the automatically recorded data, and convert- 
 ed to frequencies by means of 
 
 F. = 
 
 l 
 
 D. x 1000 
 
 l 
 
 4.75 + M. - M T 
 l I 
 
 » 
 
 where 
 
 F^ = frequency value in hertz, 
 i = contact number, 
 D = ordinate value, 
 M-£ = midreference ordinate, and 
 
 Mj = initial midreference ordinate from the sonde checkout 
 or baseline plot. 
 
 The LORAN-C values were recorded in ordinates increasing to the right 
 of the strip chart, and with ordinate 10 equal to 10 ys. "Ramp" changes 
 were also recorded. A "ramp" is defined as a shift in the recording pen 
 from ordinate 10 to ordinate 0, so that subsequent values are increased by 
 10 for each right-to-left ramp after time 0, and can be illustrated as 
 follows:

 where x = 5, x~ = 15, and x = 25 
 
 where 
 
 The LORAN-C time-delay value was derived from

 time-delay value in ordinates, 
 
 base ordinate value of the time-delay signal 
 
 at rawinsonde launch , 
 ordinate value recorded, 
 ramp change , and 
 last 30-s point to be coded. 
 
 To ensure compatibility between the manually worked up data and those 
 recorded automatically, as well as between meteorological and LORAN-C data, 
 all data were interpolated to 5-s intervals. Seven percent of the soundings 
 had to be worked up manually. These were converted to scientific units in 
 the same manner as the automatically recorded data.

 3.2.3 Computations 
 
 With minor modification, the computation program for the meteorological 
 data was the same as the one used in processing the rawinsonde data collected 
 during the Barbados Oceanographic and Meteorological Experiment (CEDDA, 1975). 
 
 3.2.3.1 Reference Correction . Temperature, relative humidity, and 
 midreference frequency (the pressure contact frequency transmitted between 
 contacts, 1,000 Hz) were corrected for high-reference frequency by use of 
 
 CF = RL|_2000 t (1) 
 
 where 
 
 CF = corrected frequency, 
 
 RF = received frequency, and 
 
 RR = received high-reference frequency. 
 
 NOTE : The meteorological data were received as periods and were converted to 
 frequencies by dividing by 5 x 10'. 
 
 3.2.3.2 Sensor Resistance . Internal, thermistor, and hygristor 
 resistances of the sonde were computed as follows: 
 
 Internal resistance 
 
 m MR x RZERO _ 
 b 2000. - MR X U ' Uy:3 ' U; 
 
 where 
 
 B = internal resistance in ohms, 
 MR = midreference frequency corrected by use of eq. (1), and 
 RZERO = the value of the midreference resistor (47,775 ohms; 
 maximum error = 0.1 percent). 
 
 Thermistor resistance 
 
 TR . 2000. x (B + TF x 0.095) . (B + TF x O , 095) (3) 
 
 where 
 
 TF 
 
 TR = thermistor resistance in ohms, 
 
 B = internal resistance from eq. (2), and 
 TF = corrected temperature frequency from eq. (1) 
 
 Hygristor resistance 
 
 R . 2000. x (B + HF x 0.095) . (B + m x 0095) (4) 
 
 rlr 
 
16 
 
 HR - 1 - 2 X 10 " X R , (5) 
 
 1.2 x 10 - R 
 
 where 
 
 HR = hygristor resistance, 
 
 B = sonde internal resistance from eq. (2), and 
 HF = corrected humidity frequency from eq . (1). 
 
 Equation (5) was necessary because of the 1.2-megohm resistor placed in 
 parallel with the hygristor. Note that R was sometimes equal to or greater 
 than 1.2 x 10" ohms; HR was then set at 1.2 x 10 , which can be used as a 
 limiting value for HR in all cases. 
 
 3.2.3.3 Temperature . Indicated temperature in degrees Celsius is 
 given by 
 
 t= ^^ 273.00 , (6) 
 
 [9.1217420 + log 1() (^q)] 2 " 27.37098 
 
 where 
 
 TR = thermistor resistance from eq . (3), and 
 R30 = resistance of the thermistor at 30°C (furnished by the factory 
 
 for each thermistor and one of the manual inputs provided in the 
 field for processing each sounding: usually about 14,000 ohms.) 
 
 A calibration correction was added to the indicated temperature to 
 obtain the corrected temperature, ct, 
 
 ct = t - 0.278246 - 0.00314038t + 0.000277829t 2 + 0. 00000367975 3 , (6a) 
 
 where the constants were determined from data furnished by the manufacturer. 
 All thermistors used during IFYGL were required to conform to this calibra- 
 tion curve within 0.1°C. 
 
 Absolute temperature was obtained from 
 
 T = ct + 273.15 
 
 3.2.3.4 Relative Humidity . Relative humidity was computed in three 
 steps. First, 
 
 [4.733 - log (f|r)] 
 RH25 = 110. - antilog j-z — — — ^^ — , (7) 
 
 where 
 
 RH25 = relative humidity for a temperature of 25°C, 
 HR = hygristor resistance from eq. (5), and 
 
17 
 
 R33 = hygristor resistance at 33 percent relative humidity (furnished 
 
 by the manufacturer for each lot of hygristors; about 10,000 ohms). 
 
 The hygristor lot number was stamped on the lid of each hygristor and was one 
 of the manual inputs for each sounding. 
 
 Second, a calibration correction was applied to RH25 by means of 
 RHTA = A + B x RH25 + C x RH25 2 + D x RH25 3 
 
 (8) 
 
 where A, B, C, and D are calibration constants determined for the particular 
 lot of hygristors from information furnished by the manufacturer, including 
 corrections for inaccuracies in eq. (7). The calibration constants are list- 
 ed in table 3.

 Third, RHTA was corrected for departure from 33 percent relative 
 humidity and a temperature of 25°C by use of 
 
 RHT = RHTA + 
 
 c(RHTA - 33.) + (t - 25.) 
 RHTA 
 
 (9) 
 
 where 
 
 RHT = relative humidity at ambient temperature, 
 c = 0.25 if RHTA > 33, 
 c = 0.03 if RHTA < 33, and 
 t = temperature from eq. (6). 
 
 At low temperatures and humidities, the correction term in eq . (8) 
 extends beyond the data from which it was derived and becomes unrealistic. 
 Therefore, a variable cutoff was used, which gave minimum output humidity 
 = 8.0 - 0.1 t, or 10 percent, whichever was greater. 
 
 3.2.3.5 Thermistor Lag Correction . The thermistor lag coefficient 
 was computed from the following formula, derived by L. D. Sanders and 
 J. T. Sullivan of CEDDA from data provided by the National Weather Service: 
 
 A - 9.77 (pv) 
 
 -0.43 
 
 (10) 
 
18 
 
 where 
 
 T 
 
 q 
 
 v 
 
 P 
 
 lag coefficient of the thermistor in seconds, 
 air density" in kilograms per cubic meter, 
 
 0.34837 P 
 
 T(l. + 0.000608q) 
 
 ambient air temperature in degrees Kelvin, 
 specific humidity in grams per kilogram, 
 rate of rise of rawinsonde in meters per second, and 
 atmospheric pressure in millibars. 
 
 (10a) 
 
 The basic correction equation is (Middleton and Spilhaus, 1953, 
 
 d8 -1 
 
 dt 
 
 .(e _ Y - et ) 
 
 A O 
 
 p. 65) 
 (11) 
 
 where 
 
 = indicated temperature at time t, 
 t = time from initial time, 
 X = lag coefficient from eq. (10), 
 Y = true temperature at initial time, and 
 3 = temperature lapse rate with respect to time; assumed 
 constant over a short time interval. 
 
 The true temperature at time t is, of course, 
 
 Y = Y Q + St 
 
 (12) 
 
 Combining eqs. (11) and (12) gives 
 
 Y - e + xf 
 
 (13) 
 
 Equation (13) can be approximated for finite differences by 
 
 (14) 
 
 where 
 
 n = sequence number of data point, and 
 t = time of data point from launch. 
 
 For the IFYGL data. 
 
 t „ , - t , = 10 seconds , 
 n+1 n-1

 Equation (14) was used in lag-correcting the thermistor data after the 
 transfer equations and calibration corrections had been applied. The use of 
 a 10-s At results in a small amount of smoothing at the lower levels (less 
 than about 200 mb), where the lag coefficient is less than 10 s, and a slight 
 increase in roughness at higher levels. For initializing, the lag correction 
 computed for n = 7 was also used for the preceding points. 
 
 3.2.2.6 Hygristor Thermal-Lag Correction . The thermal lag correction 
 for the IFYGL hygristor data was the same as the one used for the BOMEX data 
 (CEDDA, 1975), except that the ventilation rate of the hygristor was 0.9 times 
 the rate of rise. The lag coefficient was computed from 
 
 34 9 -0 4 
 
 A = n , [or 34.9 (pV) U '*] , (15) 
 
 (pV) U ^ 
 
 where 
 
 A = thermal lag coefficient of hygristor in seconds, 
 
 p = air density in kilograms per cubic meter; eq. (10a), 
 
 T = ambient air temperature in degrees Kelvin, 
 
 q = specific humidity in grams per kilogram, and 
 
 V = ventilation rate of hygristor in meters per second. 
 
 The basic correction equation is the same as for the thermistor, but 
 the problem is the reverse because the true air temperature is known and the 
 indicated temperature (hygristor temperature) must be determined. Therefore, 
 eq. (11) must be integrated for 6=6 when t=0. This gives 
 
 e = e e" t/X + 3t + (y - 3A)(1 - e" t/X ) , (16) 
 
 o o 
 
 where 
 
 6 = temperature of hygristor at time t, 
 6 Q = temperature of hygristor at time zero, 
 Y = air temperature at time zero (determined from thermistor output) , 
 
 Y„ Y„ i 
 
 t - t , ' 
 n n-1 
 
 n = sequence numbers of data points, 
 
 Y n > Yn-1 = a ^- v temperature at two adjacent data points, and 
 t n , t n _^ = times at adjacent data points (the interval being 
 normally 5 s for the IFYGL data) . 
 
 Note that if 6 = y , eq. (11) reduces to 
 o o 
 
 6 - y = -3A(1 - e" t/A ) 
 which is eq. (3.6) given by Middleton and Spilhaus (1953, p. 65).

 3.2.3.7 Wind Computations . The winds were computed from pairs of 
 LORAN-C time-delay values. 
 
 The LORAN-C signals were frequently cluttered by two types of jump in 
 the time-delay value (Sullivan and Matejceck, 1975). The "sudden lane jump" 
 was an increase or decrease by a multiple of 10 us between adjacent samples. 
 This was easily detected by software, and the spurious change was deleted. 
 The "slow lane jump" was a spurious rapid change spread over a period of 10 
 to 30 s or more. Most of these were corrected by manual input, but some 
 minor ones were missed and were corrected automatically by the following 
 procedure. 
 
 Standard errors of estimate were computed for each 5-s data point from 
 time t = 30 s to the end of the data. The standard error of estimate of Y on 
 X is 
 
 i 
 
 II(Y-Y ) 2 
 
 s y.x - y m • (i8) 
 
 From the least-squares regression line, 
 
 Y Q ^ = A + BX , (19) 
 
 est 
 
 From eqs. (18) and (19) is obtained (Spiegel, 1961, p. 250) 
 
 sj = (ZY 2 - AZY - BIXY)/N , (20) 
 
 where 
 
 Y = LORAN-C time delay in microseconds, 
 
 X = time from start of regression period in seconds, 
 
 N = number of cases in the regression period 
 
 = 13 for the 1-min regression periods used, 
 S was computed for 1-min periods centered on each 5-s data point 
 
 in turn, and 
 A and B are coefficients of the least-squares regression line. 
 
 2 
 A lane jump was assumed to have occurred when Sy.x t. 0.75, an empirical 
 
 value determined from samples of the data. The signal was assumed to have re- 
 turned to normal when S£ again became less than 0.75. 
 
 Bias introduced by the lane jump was removed by assuming that the 
 beginning of the jump was detected at time t and the end at t + At (fig. 5). 
 An estimate of Y t+ ^ t was computed from 
 
 VAt " <Y t-10 + V5 + V /3 - + B t-35 At '

 Figure 5. — Illustration of introduction 
 of bias by lane jump. 
 
 where B t _35 was determined from the regression eq. (19) for the 1-min period 
 ending at the data point before the slow jump was detected. The bias was 
 then computed from 
 
 Blas = Vat " * • 
 
 and all time delays from t + At to the end of the sounding were corrected by 
 
 Y . = Y . - Bias 
 time time 
 
 After lane jumps had been corrected, the data were smoothed by replacing 
 each 5-s time-delay value with 
 
 Y = A + Bt + Ct 2 
 t ' 
 
 where coefficients A, B, and C were determined from a 2-min sample of data 
 centered on time t. For each point in the sample it was required that 
 
 (Y - Y t )' 
 
 2.5 
 
22 
 
 with up to half the sample allowed to be discarded. Final values of A, B, and 
 C used for smoothing were computed from the data points that passed the test. 
 
 The edited time-difference values were converted to X and Y values, as 
 well as to latitude and longitude, by an algorithm similar to that described 
 by Acheson (1974). The winds were computed from the change in positions with 
 respect to time. The u and v components were computed from the x and y 5-s 
 displacements (where t is time) as follows. 
 
 For 5-s data: 
 
 fi _ X (t+5) " X (t-5) 
 t " 10. 
 
 . y (t+5) " y (t-5) 
 t 10. 
 
 For 50-mb and p* (10-mb) surfaces: 
 
 u. = 
 
 x (t+30) x (t-30) 
 
 t 60. 
 
 ^ y (t+30) y (t-30) 
 V t 60. 
 
 3.2.4 Adiabatic Plots and Microfilm Listing 
 
 The final step in the second-stage processing was the preparation of 
 adiabatic plots on 35-mm microfilm (fig. 6) and a listing of all parameters. 
 The plots show, at 5-s intervals, wind speed and direction, u and v compo- 
 nents, relative humidity, air temperature, and dewpoint temperature. 
 
 4. ARCHIVE FORMAT AND DATA INVENTORY 
 
 Three sets of data were generated for the archive: 5-s data, 10-mb 
 surfaces, and 50-mb surfaces, the last two computed from the 5-s data by 
 interpolation between the two values on each side of the surface. All are 
 available on magnetic tape. The data are also plotted in the form of adia- 
 batic charts on 35-mm microfilm, with accompanying listings of all parameters 
 
 The data set consists of 2,953 rawinsonde soundings, 259 of which had 
 to be worked up manually. Flight release numbers are numbers assigned in the 
 field and are not necessarily consecutive because of deletion of soundings 
 that could not be processed. The values stored at time are derived from 
 surface instrumentation rather than the sonde. Although all parameters are 
 archived at a resolution of 5 s, there is considerable overlap in the LORAN-C 
 winds, and their actual resolution is about 1 min.

 4.1 Tape Format 
 
 Each observation consists of a variable number of 144 character records 
 The first 14 characters of each record are identifiers: station number, year, 
 Julian day, hour, type and sequence number. The first 10 records include the 
 following information: 
 
 Launch number 
 
 Type run (automated or manual) 
 Station name and coordinates 
 Nominal and actual release times 
 (Julian day, hour, minute) 
 Number of data points (NPTS) 
 Print image column headings 
 
 The tapes were generated using FORTRAN. Fields are right justified 
 with high order positions blank filled. 
 
 The following notations are used: 
 
 x = any numeric or alphanumeric character 
 
 - = an "11" punch in the card or the equivalent tape configuration 
 A = blank configuration on tape 
 Field = any position or group of positions used to describe an element

 4.2 Material in Temporary Storage 
 
 The output of the TRANS program, which was used as input to the EDIT 
 program, will be held in the archive for a period of 5 years. The data format 
 is as follows: 
 
 800 BPI - CDC scope internal format - labelled tape. 
 File 1-80 character label - in display code. 
 File 2 - and subsequent files (all floating point) . 
 Record 1 - flight header information. 
 Record 2 - baroswitch calibration. 
 
 Record 3 - first 100 cycles of data, where a cycle consists of time, 
 high reference, pressure, temperature, humidity at approx- 
 imately 0.8-s intervals; all values except time in fre- 
 quencies. 
 Record n - last record with meteorological data (-l.fill) 
 Record n+1 - first 400 records of Cape Fear-Nantucket time differences 
 
 (2-s intervals). 
 Record n+2 - first 400 records of Cape Fear-Dana time differences 
 (2-s intervals) . 
 
32 
 
 Record n+3 - second 400 records of Cape Fear-Nantucket time differ- 
 ences. 
 
 Record n+4 - second 400 records of Cape Fear - Dana time differences, 
 
 and so on, to the end of the flight. 
 
 An end-of-file follows each sounding, and a double end-of-file marks 
 the end of the last sounding.
