OLYMPEX logoThe GHRC published the GPM Ground Validation CAX1 Radar CFradial format OLYMPEX dataset (http://dx.doi.org/10.5067/GPMGV/OLYMPEX/XBAND/DATA301). This dataset consists of radar parameters, such as Radar reflectivity, Doppler velocity, Doppler width, Differential reflectivity, and Signal quality index, provided on a 0.4 to 1.0 km spatial resolution within the OLYMPEX field campaign study region in the state of Washington. These data were obtained for the GPM Ground Validation OLYMPEX field campaign by the dual polarization X-band “CAX1” portable scanning...

The GHRC published the GPM Ground Validation National Mosaic and Multi-Sensor QPE (NMQ) System IPHEx dataset (http://dx.doi.org/10.5067/GPMGV/IPHEX/NMQ/DATA101). This dataset consists of six different data products: precipitation rate, hourly rainfall accumulation, daily rainfall accumulation, hybrid scan reflectivity, three-dimensional reflectivity, and vertically integrated liquid content estimates. These data products were created using the NOAA NMQ System which ingests Weather Surveillance Radar 88 Doppler (...

The Global Hydrology Resource Center (GHRC) DAAC has published all four of the GPM Ground Validation NEXRAD Level III IFloodS datasets. The purpose of the IFloodS campaign was to help support the ground validation of the Global Precipitation Measurement (GPM). NEXt Generation Weather RADar system (NEXRAD) Level-II data were previously published.  These Level-III NEXRAD precipitation products were gathered from Unidata for four NEXRAD stations in the vicinity of the IFloodS campaign during March 29, 2013 through June 18, 2013. These datasets contain data files of digital instantaneous precipitation rate (DPR) and storm total accumulation estimates (DTA) in NIDS binary format. For a complete archive of data from each station beyond the IFloodS time period, please...

GHRC DAAC has published the NOXP IPHEx dataset: http://dx.doi.org/10.5067/GPMGV/IPHEX/NOXP/DATA101

The GPM Ground Validation NOAA X-band dual-Polarimetric radar (NOXP) IPHEx dataset consists of differential reflectivity, differential phase shift, co-polar cross correlation, radial Doppler velocity, spectrum width, signal index, melting layer index, reflectivity, drop size distribution, and rainfall rate observations, as well as other radar parameters, collected by NOXP mobile radar during the GPM Integrated Precipitation and Hydrology Experiment (IPHEx) field campaign. The IPHEx field campaign occurred in the Southern Appalachians, spanning into the Piedmont and Coastal Plain regions of North Carolina. The NOXP radar, operated by the NOAA National Severe...

The GPM Ground Validation Daily Precipitation OLYMPEX dataset is now available

http://dx.doi.org/10.5067/GPMGV/OLYMPEX/MULTIPLE/DATA301

The GPM Ground Validation Daily Precipitation Olympic Mountain Experiment (OLYMPEX) dataset consists of a single netCDF-4 data file containing estimates of daily precipitation, both rainfall and snowfall amounts, on a 1/32 degree spatial resolution grid covering the extent of the OLYMPEX field campaign region in the Olympic Mountains of the state of Washington. This data product was created for the GPM Ground Validation OLYMPEX field campaign. These VIC precipitation estimates are based on NOAA WSR-88D...

GHRC DAAC has published the IFC Stream Flow IFloodS dataset: http://dx.doi.org/10.5067/GPMGV/IFLOODS/GAUGES/DATA201

The GPM Ground Validation Iowa Flood Center (IFC) Stream Flow IFloodS dataset was obtained from the IFC during the Iowa Flood Studies (IFloodS) field campaign that extended from March 31, 2013 through June 30, 2013. The main goal of IFloodS was to evaluate how well the GPM satellite rainfall data can be used for flood forecasting. The IFC monitors stage levels using sensors attached to the side of bridges throughout Iowa. The sensor data are downloaded from the Iowa Flood Information System (IFIS) as support data for the IFloodS campaign. The IFC Stream Flow data were...
