Simultaneous Observations of Precipitation from a Vertically Pointing S-Band Profiler Radar and a Horizontally Looking C-Band Dual Polarization Radar: A Microphysical Perspective

Weather radars have been proven to be a valuable asset for accurately characterizing precipitation over large domains. Dual-polarization and dual-frequency measurements from weather radar can be used for a variety of microphysical retrievals that are crucial for accurate parametrization of precipitation characteristics [1]. This study presents a microphysical investigation of a convective precipitation event that occurred near Huntsville, Alabama on December 11, 2021 and leverages on complementary observations from a vertically pointing S-Band Profiler Radar and a scanning dual-polarization C-Band Radar. The ultimate goal is to understand and better resolve the critical atmospheric physical processes governing convective precipitation events that is needed to help guide the development and choice of model physics in NOAA’s operational model forecast systems which is one of the main objectives of the NOAA’s Precipitation Prediction Grand Challenge (PPGC).
