The GHRC DAAC published the GPM Ground Validation Dual-frequency Dual-polarized Doppler Radar (D3R) IPHEX dataset (DOI: http://dx.doi.org/10.5067/GPMGV/IPHEX/D3R/DATA101). This data was collected from May 3, 2014 to June 15, 2014 during the GPM Ground Validation Integrated Precipitation and Hydrology Experiment (IPHEx) held in North Carolina. The D3R is a fully polarimetric, scanning weather radar system operating at the nominal frequencies of 13.91 GHz and 35.56 GHz covering a maximum range of 30 km. The GPM Ground Validation Dual-frequency Dual-polarized Doppler Radar (D3R) IPHEx dataset is available in netCDF format.
