Evaluation of a polarimetric attenuation correction algorithm for NASA D3R observations during the IFloodS field campaign

As a joint Earth-observing mission between NASA and the Japan Aerospace Exploration Agency (JAXA), the Global Precipitation Measurement (GPM) Core Observatory was launched on February 27^th, 2014. The GPM sensors can cover most of the globe, and improve precipitation observations at higher latitude, compared to the Tropical Rainfall Measuring Mission (TRMM). As an indispensable part of all precipitation satellite missions, Ground Validation (GV) is critical for demonstration and evaluation of space-based precipitation data products. As part of the GV activities, a ground-based Dual-frequency Dual-polarization Doppler Radar (D3R) was developed. D3R is operating at the nominal frequencies of Ku and Ka band to match the operating frequencies of space-based GPM Dual-frequency Precipitation Radar (DPR).
