The NASA Global Hydrology Resource Center (GHRC) DAAC published the Dual-frequency Dual-polarized Doppler Radar (D3R) instrument micro article. D3R is a mobile, dual-frequency, fully polarimetric Doppler radar that operates primarily in support of the Global Precipitation Measurement (GPM) mission Ground Validation program. It operates at two frequencies: 13.91 GHz (Ku-band) and 35.56 GHz (Ka-band). These measurement frequencies allow D3R to observe precipitation types ranging from heavy rainfall to snow. The polarimetric and Doppler capabilities of D3R provide further insight into the characteristics and dynamics of precipitation systems. The micro article provides an overview of D3R and its applications to support GHRC’s current and future D3R datasets.
