C. June 1975 ACKNOWLEDGMENTS This atlas was prepared under the direction of James A. Almazan, CEDDA. The computer plots were produced by Mel Craddock at the National Climatic Center. INTRODUCTION During the Barbados Oceanographic and Meteoro- logical Experiment (BOMEX), conducted in the sum- mer of 1969, data were gathered by aircraft, ships, and buoys, supplemented by satellite data and observations made on the island of Barbados. Details of the experi- ment are given in BOMEX Field Observations and Basic Data Inventory issued in 1971 by the BOMAP Office (now Center for Experiment Design and Data Analysis), and the scientific objectives of BOMEX have been described by J. P. Kuettner and J. Holland ("The BOMEX Project," Bulletin of the American Meteorological Society, Vol. 50, No. 6, 1969, pp. 394- 402). The vast amount of data collected, after processing and validation by the Center for Experiment Design and Data Analysis of NOAA's Environmental Data Service, has been placed in the BOMEX Permanent Archive at the National Climatic Center, Asheville, N.C. Among these data are surface measurements obtained with sensors mounted on a boom extending from the bow of each of the five BOMEX ships approximately 10 m above the sea surface, and observations made with the specially designed Boundary Layer Instrument Package (BLIP), which was launched from four of the ships. Presented in this atlas are day-to-day time series displays of the boom and BLIP data for BOMEX Period III, June 19 to July 2, 1969, when the five ships occupied positions at the corners and in the center of the BOMEX square array as shown in the accompanying figure. Included also are ship operation mode and synoptic data based on standard meteorological obser- vations. Blanks indicate that data were missing or de- leted in editing, or that the number of samples was not sufficient to derive average values. The last applies to the BLIP data for the Rainier, and BLIP data are also missing for the Rockaway, which did not carry the special instrument package. SURFACE DATA The boom surface data presented here were ob- tained by all five ships, the Discoverer, Mt. Mitchell, Oceanographer, Rainier, and Rockaway. They consist of 10-min averages derived from the original 30-s samples of dry-bulb temperature, sea-surface tempera- ture, windspeed, and specific humidity computed from the vapor pressure obtained via Teten's equation (Handbook of Meteorology, McGraw-Hill Book Co., N.Y., 1945, p. 343.) Wind direction is shown as hourly averages. The manually recorded synoptic data are plotted in the standard World Meteorological Organiza- tion code, and show the total amount of cloud cover, type of clouds and their amounts, and present and past weather. A straight line at the bottom of each display shows periods when the ship was operating in a drifting mode; a blank indicates that the ship was steaming to maintain station. This information is included because the wind values are not corrected for ship motion. The 10-min averages, which are now available from the BOMEX Permanent Archive, were derived via a second-order least-squares method. No further editing was done for purposes of this atlas, and these values were also used in forming the hourly averages of wind 61' 60' 59- S8" 57" 56' SS W 53- 52* m- 19 18" 17' 18 \ OCEANOGRAPHER , rainier) 16 1 16' IV * ^^ ROCKAWAY 15" -r- 14 13 B1RBA00S k — DISCOVERER 1 1 1?'

For a detailed description of the editing procedures, the reader is referred to the documentation that accompanies the archived data. BLIP DATA The Boundary Layer Instrument Package was essentially a multichannel radiosonde launched by means of a tethered balloon from the afterdeck of each of the four corner ships. The balloon was generally lifted to a height of 300 m, left at that level for several hours, and then retrieved. Dry- and wet-bulb tempera- tures, windspeed, wind direction, relative humidity, and pressure were measured at a rate of three samples per second (sps). The pressure sensor was a modified radiosonde baroswitch that provided only six or seven discrete readings from the surface to 300 m. The wind- speed was direcdy proportional to the frequency of rotation of a three-cup anemometer. The wind direction was obtained by special instrumentation that measured the angle of the package, which was always pointed into the wind, from magnetic north. A detailed description of the measuring system has been given by J. A. Almazan ("The BOMEX Boundary Layer Instrument Package," Preprints, Second Symposium on Meteoro- logical Observations and Instrumentation, March 27- 30, 1972, American Meteorological Society, 1972, pp. 138-144). Before archiving, the 3-sps BLIP data were edited by means of data '"windows," the data were reduced to 1-sps format, and the quality of the data was noted for each sample. The 1-min averages of dry-bulb tem- perature, specific humidity, and windspeed, as well as the hourly averages of wind direction, presented in this atlas were derived from the 1-sps archived data, which were further edited by rejection of values based on the criterion of one standard deviation. In computing the specific humidity, the vapor pressure was first obtained from the dry- and wet-bulb temperature differences via the Groft-Gratch equation (Smithsonian Tables, 1951, p. 350), and the specific humidity was then derived from q = 6.22e/ (p — 0.378e), where q is the specific humidity, p is the pressure, and e is the vapor pressure. The mean pres- sure value at 300 m during BOMEX Period III was 980 mb, and this is the value used in the calculation. It is approximate, since the baroswitch gave only gross measurements of the pressure, and there was no direct measurement of the height. A primary purpose in presenting the BLIP data in this atlas is to give a first estimate of the character, quality, and length of these unique time series, which lend themselves to spectral analysis, and to display the effects of varying synoptic conditions on temperature, humidity, and wind at the surface and at 300 m. The data obtained during instrument ascent and descent are not included here. The archived data, however, provide an opportunity for constructing profiles for various synoptic conditions, as has been done in selected cases by C. F. Ropelewski of the Center for Experiment Design and Data Analysis in NO A A Technical Memorandum EDS BOMAP-12, "Profiles in the Lowest 300 Meters of the Marine Tropical Boundary Layer."
