GPM GROUND VALIDATION DUAL-FREQUENCY DUAL-POLARIZED DOPPLER RADAR (D3R) IPHEX
The GPM Ground Validation Dual-frequency Dual-polarized Doppler Radar (D3R) IPHEx data set contains radar reflectivity and doppler velocity measurements. The D3R was developed by a government-industry-academic consortium with funding from NASA's Global Precipitation Measurement (GPM) Project. It operates at the ku (13.91 GHz ± 25 MHz) and ku (35.56 GHz ± 25 MHz) frequencies covering a fixed range from 450 m to 39.75 km. The instrument's data are available in netCDF-4 format with browse imagery available in PNG format.
