Dual-polarization, Dual-frequency Doppler Radar (D3R)

D3R is NASA's Ka/Ku Dual-polarization, Dual-frequency, Doppler mobile radar. During the winter of 2023, D3R was located in Storrs, CT to support ground observations for the Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms ((IMPACTS) In a synergistic effort GPM has deployed a suite of precipitation-measuring instruments to the University of Connecticut (Storrs, CT). The instruments were deployed on Dec. 18, 2022 and it is envisaged that they will remain there through mid-March of 2023. This year GPM GV will provide instruments at two site: GAIL and D3R.
