The GPM Ground Validation NASA S-Band Dual Polarimetric (NPOL) Doppler Radar IPHEx dataset was collected during the GPM Ground Validation Integrated Precipitation and Hydrology Experiment (IPHEx) field campaign conducted in South Carolina from April 27, 2014 through June 16, 2014. The NPOL Doppler Radar scanned in high-resolution Plan Position Indicator (PPI), Range-Height Indicator (RHI), and PPI Sector (PPS) scan modes and provided measurements of precipitation in liquid, mixed, and ice phases. Data files are available in tarred universal format (UF) files, and browse images are available in compressed PNG files.
