Validate Algorithms for the Determination of Rainfall Rates from SSM/I Microwave Satellite Imagery.
Abstract
Since the end of September, our primary activities have been (a) amassing an extensive catalog of radar and raingage data over our primary and secondary validation sites that correspond to SSM/I overpass times occurring between July 19 and Sept. 30, 1987, (b) ordering radar and calibrating raingage data for cases in this catalog, (c) ordering the SSM/I data for the same cases, (d) writing the software necessary for unpacking calibrated rain data from the United Kingdom, (e) upgrading the navigation of radar bins, based upon the geometry of radar beam propagation and the geodetic formulae of Sodano (Bull. Geodesique, 1965), and (f) imaging the 25 km resolution radar rain rate fields produced by our data merging programs (see Validation Software section). We are just beginning to analyze the radar from our primary validation sites, comparing this data with the limited number of orbits of SSM/I data so far received. We are also continuing our cooperation with scientists of the Severe Storms Branch of NASA/Goddard Space Flight Center in order to expedite the radiative transfer modeling necessary for the analysis and improvement of the current rain rate algorithm.
