This federal contract award, valued at $367,584.00, was made by the National Aeronautics and Space Administration (NASA) to The Regents of the University of Colorado, doing business as the University of Colorado Office of Contracts and Grants Division. The objective of the research is to quantify melting layer attenuation and raindrop size distribution variability within the instantaneous field-of-view of the Dual-Frequency Precipitation Radar (DPR) on the Global Precipitation Measurement (GPM) mission, and assess the impact of these factors on DPR observations and retrieval algorithms. The research will leverage data from NASA's ground validation field campaigns, including IFLOODS, IPHEX, and OLYMPEX, to develop a DPR radar simulator that can relate microphysical measurements to DPR measurements. This is a grant for research that does not have a set-aside designation, and it supports NASA's broader efforts to improve precipitation measurement and retrieval from the GPM satellite mission.
