Abstract:

This final report describes work performed with the Chilbolton dual polarization radar under contract number AFOSR-86-0193. In addition to measuring the conventional radar reflectivity factor, Z, this radar can measure the differential reflectivity, ZDR, which senses the shape of the precipitation particles. ZDR may be used to differentiate water from ice, to measure the mean size of raindrops and to provide more accurate estimates of rainfall rates. This report is divided into five self-contained parts, each with its own set of diagrams and references. The first four parts consider analysis of Z and ZDR data obtained in 1983 and 1984 the final part describes the first results of a new parameter observed with the reconfigured radar in the fall of 1987.
