Description:As part of the GARP Atlantic Tropical Experiment (GATE), quantitative precipitation observations, covering an array of ships centered at 8°30f N. latitude and 23°30f W. longitude, were made during the summer of 1974 using four C-band digital radars complemented by shipboard rain gages. This report describes the system of programs that was developed to derive rainfall estimates from the individual radars, to correct these estimates for such effects as atmospheric attenuation, to navigate and merge the estimates from the individual radars within a master array, and to integrate the instantaneous estimates for hourly periods. The resultant data, consisting of hourly rainfall amounts for a Cartesian network of 4-km square data bins, were archived both on magnetic tapes and microfilm. A sample rainfall map is included. The quality of the data is excellent and the problems identified in the use of the data have been very few and minor, leading us to believe that the precipitation processing system was successful and that all crucial refinements were made to improve the quality of the data.
