GHRC News

The NASA Global Hydrology Resource Center (GHRC) DAAC published the GPM Ground Validation CAX1 Radar RB5 format OLYMPEX dataset (http://dx.doi.org/10.5067/GPMGV/OLYMPEX/XPOL/DATA201). 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 SELEX Meteor 60DX10 Compact Weather (CAX1) 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 (ECCC) to support the OLYMPEX field campaign. These data are available in RB5 binary and PNG formats from November 13, 2015 to April 20, 2016. It should be noted that the RB5 data format is proprietary and requires access to read code from SELEX. We encourage users wanting to use the CAX1 data to instead use the CAX1 ODIM or CFradial formatted data. 

The NASA Global Hydrology Resource Center (GHRC) DAAC published the GPM Ground Validation Global Satellite Mapping of Precipitation (GSMaP) IFloodS dataset (http://dx.doi.org/10.5067/GPMGV/IFLOODS/TMI/DATA201). This dataset consists of rainfall rate estimates from the GSMaP project. The GSMaP global rain rate maps are derived by a collection of algorithms that utilize microwave (MW) radiometer data and geostationary Infrared (IR) data. The GSMaP Precipitation data product is provided on a 0.1 degree spatial resolution every hour and was made available for use during the Global Precipitation Measurement (GPM) Ground Validation Iowa Flood Studies (IFloodS) field campaign. These data are available in netCDF-4 and binary formats from April 22, 2013 through June 30, 2013. The near real-time GSMaP data can be obtained from the JAXA GSMaP web page.

The NASA Global Hydrology Resource Center (GHRC) DAAC published the GPM Ground Validation GOES 14 Visible and Infrared Images IPHEx dataset (http://dx.doi.org/10.5067/GPMGV/IPHEX/GOES14/DATA101). This dataset contains visible and infrared images from the GOES 14 Imager collected during the Integrated Precipitation and Hydrology Experiment (IPHEx) field campaign in the southeast region of the United States. The GPM Ground Validation GOES 14 IPHEx dataset files are available in PNG format at 1 minute intervals, for all dates between May 8, 2014 and May 24, 2014.

A GHRC Bi-Annual Newsletter for the time period of September - April is now available. Highlights include a NASA Webinar presentation, new micro articles and data recipes that have been released, data publication metrics, and more!

The NASA Global Hydrology Resource Center (GHRC) DAAC published the GPM Ground Validation GOES 15 Visible and Infrared Images OLYMPEX dataset (http://dx.doi.org/10.5067/GPMGV/OLYMPEX/GOES15/DATA101). This dataset contains visible and infrared images from the GOES 15 Imager during the GPM Ground Validation Olympic Mountains Experiment (OLYMPEX) field campaign held in the Pacific Northwest. The GOES 15 images are available for all dates between November 5, 2015 and May 1, 2016 at 15 minute intervals. The GPM Ground Validation GOES 15 OLYMPEX dataset files are available in PNG format.
