Validate Algorithms for the Determination of Rainfall Rates from SSM/I Microwave Satellite Imagery.
Abstract
During the past two months, our research activities have included (a) updating our catalog of rain cases observed by the SSM/I coincident with radar coverage from our primary or secondary sites, (b) ordering SSM/I, radar, and raingage data for the aforementioned cases, (c) processing the gage-calibrated United Kingdom radar data and merging this data with SSM/I observations to create statistics files, (d) developing software for deriving gage calibration coefficients to be used with uncalibrated radars, (e) writing routines for applying BMDP scatterplot and step-wise multiple linear regression software to the SSM/I-ground truth statistics files, and (f) adapting the NCAR SCD plotting package for the contouring of data fields and the production of other high-quality graphics. In addition, software for creating vertical integrals of volume-scan radar data has been nearly completed. Codes are also under development (with the cooperation of Dr. Gene Poe of NRL) for constructing antenna pattern-matching filters. We are continuing our collaboration with Dr. Chris Kummerow and his colleagues at the Severe Storms Branch of NASA/Goddard Space FLight Center. By this cooperative effort we hope to expedite the radiative transfer modeling necessary for the analysis of SSM/I-ground truth data sets and improve the current rain rate algorithm.
