Barbados Oceanographic and Meteorologic Experiment

What is BOMEX

The following text is taken from the Introduction of the BOMEX Field Observations and Basic Data Inventory publication, NOAA (1971).

The principal objective of the Barbados Oceanographic and Meteorological Experiment (BOMEX) was to measure the rate of exchange of the "properties" heat, water substance, and momentum between the tropical ocean and the atmosphere. As an experimental prototype of the basic grid element of a global observation system, an area 500km x 500km east of Barbados was chosen for field operations, during which data were gathered by ships, aircraft, and buoys, supplemented by satellite data and land-based observations on the island of Barbados.

The field operations were divided into four observation periods of 13 to 18 days each to support the two major investigations: the air-sea interaction investigation, conducted during BOMEX Period I, May 3 to May 15, Period II, May 24 to June 10, and Period III, June 19 to July 2, 1969; and the investigation of tropical convective systems, conducted during Period IV, July 11 to July 28, 1969. During the first three periods, observations, with few exceptions, were made only within the BOMEX square , with five ships occupying fixed positions at the four corners and in the center of the square. For the investigation of tropical convective systems during Period IV, the latitudinal spread of the BOMEX fixed-ship array was extended southward to incorporate the Intertropical Convergence Zone (ITCZ) and aircraft were used in a more flexible manner to explore cloud systms over a much greater extent of the northern tropical Atlantic.


Currently available from Steve Krueger are the radiosonde data from each of the five ships in the BOMEX array for BOMEX observation period III (June 20 to July 2, 1969).

These data were used by Nitta and Esbensen (1974: Mon. Wea. Rev.) and others to estimate the large-scale mass, heat, and moisture budgets. Unfortunately, the results of these budget analyses at a daily or more frequent time interval no longer exist in tabulated form, to the best of Steve's knowledge.

At some future date, it is planned to reanalyze the radiosonde data to obtain a time series of the large-scale budgets. Volunteers?
