GPM GROUND VALIDATION NEXRAD LEVEL II KARX IFLOODS V1

The GPM Ground Validation Next Generation Weather Radar (NEXRAD) Level II IFloodS datasets were collected from four sites (see Table 1) from March 29, 2013 to June 18, 2013 for the GPM Ground Validation Iowa Flood Studies (IFloodS) field campaign in central-northeastern Iowa. Officially, the IFloodS campaign ran from May 1 to June 15, 2013 but the NEXRAD data was collected prior to the start, allowing for the wider period of record. There are currently 160 Weather Surveillance Radar-1988 Doppler (WSR-88D) or NEXRAD sites throughout the United States and select overseas locations. The resulting data includes the base data (Level-II) and the derived products (Level-III). These Level-II datasets include three meteorological base data quantities: reflectivity, mean radial velocity, and spectrum width. The GPM Ground Validation NEXRAD Level II IFloodS data files are in a custom binary format; the visualization and decoding of the data requires specialized software. Browse imagery is available in PNG file format.
