GHRC News

IPHEx logoThe GHRC published the GPM Ground Validation Hydro-Estimator IPHEx dataset (http://dx.doi.org/10.5067/GPMGV/IPHEX/MULTIPLE/DATA401). This dataset contains rainfall rate estimates derived using NOAA’s Geostationary Operational Environmental Satellites (GOES) infrared (IR) brightness temperature data by researchers at the NOAA Center of Satellite Applications and Research’s (STAR) using the Hydro-Estimator (H-E) model. Rainfall rate estimates are produced every 15 minutes throughout the continental United States, but for this dataset, have been subsetted to the North Carolina region for the Integrated Precipitation and Hydrology Experiment (IPHEx) field campaign in support of  Global Precipitation Measurement (GPM) ground validation. These data are available in netCDF-4 format and consists of rain rate values from May 1, 2014 through June 16, 2014.

IFloodS logoThe GHRC published the GPM Ground Validation Hydro-Estimator IFloodS dataset (http://dx.doi.org/10.5067/GPMGV/IFLOODS/MULTIPLE/DATA101). This dataset contains rainfall rate estimates derived using NOAA’s Geostationary Operational Environmental Satellites (GOES) infrared (IR) brightness temperature data by researchers at the NOAA Center of Satellite Applications and Research’s (STAR) using the Hydro-Estimator (H-E) model. Rainfall rate estimates are produced every 15 minutes throughout the continental United States, but for this dataset, have been subsetted to the Iowa region for the Iowa Flood Studied (IFloodS) field campaign in support of  Global Precipitation Measurement (GPM) ground validation. These data are available in netCDF-3 format and consist of rain rate values from April 25, 2013 through June 30, 2013.

The GHRC published the GPM Ground Validation Iowa Flood Center (IFC) NEXRAD Composite IFloodS dataset (http://dx.doi.org/10.5067/GPMGV/IFLOODS/NEXRAD/DATA101). This dataset contains rain rate estimates derived using NEXt Generation Weather RADar system (NEXRAD) radars in operation during the Iowa Flood Studies (IFloodS) field campaign, in support of Global Precipitation Measurement (GPM) ground validation. NEXRAD is a network of 160 stationary S-Band radars dispersed throughout the United States and select locations abroad. Data were gathered in the vicinity of the IFloodS field campaign which took place in Iowa and surrounding areas during April 19, 2013 through June 30, 2013. This NEXRAD Composite data product is available in netCDF-4 or ASCII format with associated reflectivity browse imagery available in GIF format.

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 radar. The CAX1 radar was located at the southern tip of Vancouver Island on the Canadian Forces Base (CFB) Esquimalt Albert Head (AHD) military training area. The CAX1 radar was operated by Environment and Climate Change Canada to support the OLYMPEX field campaign. These data are available in Cfradial netCDF-4 format from November 14, 2015 through April 1, 2016.

The GHRC published its third phenomenon micro article on hurricanes, addressing one of the DAAC’s key science focus areas. This micro article introduces users to what hurricanes are, how they form, where they occur, how they are observed by instruments and what NASA project data at GHRC captures hurricane events. In addition, GHRC UWG member Dr. Jonathan Zawislak from Florida International University served as a content reviewer for this micro article. The hurricane micro article may be accessed here: https://ghrc.nsstc.nasa.gov/home/micro-articles/hurricane
