NASA's Global Hydrometeorology Resource Center Distributed Active Archive Center (GHRC DAAC) published the Global Precipitation Measurement (GPM) Ground Validation (GV) NOAA X-band Polarimetric Radar (NOXP) Integrated Precipitation and Hydrology Experiment (IPHEx) dataset. This dataset consists of differential reflectivity, differential phase shift, co-polar cross correlation, radial Doppler velocity, reflectivity, and other radar parameters, collected by NOXP mobile radar during the GPM IPHEx field campaign. The IPHEx field campaign occurred in the Southern Appalachians, spanning into the Piedmont and Coastal Plain regions of North Carolina during April 21, 2014 through June 15, 2014. The NOXP radar, operated by the NOAA National Severe Storm Laboratory (NSSL), was positioned in the Pigeon River basin of the Great Smoky Mountains of North Carolina. NOXP data are available in netCDF-3 format. The dataset includes weather condition photos taken at the NOXP radar location.
GHRC DAAC has published all four of the GPM Ground Validation NEXRAD Level III Iowa Flood Studies (IFloodS) datasets. The purpose of the IFloodS campaign was to help support the ground validation of the GPM. NEXRAD Level-II data were previously published in 2017. This dataset, consisting of two 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 digital instantaneous precipitation rate (DPR) and storm total accumulation estimates (DTA) in NIDS binary format files. For a complete archive of data from each station beyond the IFloodS time period, please utilize the NOAA archives at Amazon Web Services and Open Common Consortium. See the NOAA website at https://www.ncdc.noaa.gov/data-access/radar-data/noaa-big-data-project for more information.

The dataset consists of radar parameters such as radar reflectivity, Doppler velocity, Doppler width, differential reflectivity, and signal quality indices provided at a 0.4 to 1.0 km spatial resolution. The CAX1 radar was operated by Environment and Climate Change Canada and located at the southern tip of Vancouver Island on the Canadian Forces Base Esquimalt Albert Head (AHD) military training area. The data files are available in Cfradial netCDF-4 format.
GHRC DAAC has published the GPM Ground Validation IFC NEXRAD Composite IFloodS dataset. This dataset contains rain rate estimates derived using NEXRAD radars in operation during the IFloodS field campaign carried out to support GPM ground validation. NEXRAD is a network of 160 stationary S-Band radars dispersed throughout the United States and select locations abroad. Data from NEXRAD radars within and near the IFloodS Iowa study region were gathered during April 19, 2013 through June 30, 2013 to create this subset for IFloodS support. The NEXRAD Composite data files are available in netCDF-4 or ASCII format with associated reflectivity browse imagery available in GIF format.

On 12 March, SEDAC completed a beta release of the India Village-Level Geospatial Socio-Economic Data Set: 1991, 2001, a compilation of the finest level of administrative boundaries in India (village/town-level) and over 200 socio-economic variables collected during the Indian Census in 1991 and 2001. This dataset was developed by digitizing village/town level boundaries from the official analog maps published by the Survey of India for 2001. This dataset also utilized tabular data for 1991 and 2001 from the Primary Census Abstract (PCA) and Village Directory (VD) data series of the Indian census. The data are in Universal Transverse Mercator (UTM) 44N projection and are distributed primarily as shapefiles. Separate files are provided for each of the 28 states (number of states during 1991 and 2001 census) and combined Union Territories for 1991 and 2001.
