The NASA Global Hydrology Resource Center (GHRC) DAAC published the GPM Ground Validation Albert Head (AHD) Ground Meteorological Station (MET) OLYMPEX (

This dataset consists of precipitation rate, reflectivity, pressure, temperature, relative humidity, wind speed, and wind direction data which were measured by the MET station instruments operated by the Environment and Climate Change Canada (ECCC) and located in Albert Head, B.C., Canada. The MET station was comprised of a Vaisala FD12P Visibility Sensor, an OTT Parsivel2 Present Weather Sensor, an OTT Pluvio2 Precipitation Gauge, and a Vaisala WXT520 Weather Transmitter. The MET Station was also co-located with a CAX-1 radar to compare measurements from the MET station with the radar scans. These MET Station data files are available from November 13, 2015 through January 17, 2016 in ASCII-CSV and XML formats, with daily browse images of precipitation rate plots in PNG format.

This dataset contains visible and infrared images in 3 sizes (FULL, CONUS, and EXT) obtained from the GOES 13 Imager during the Integrated Precipitation and Hydrology Experiment (IPHEx) field campaign that took place in the southeast region of the United States. This collection of GOES 13 images are available at 30 minute (EXT and CONUS) and 3 hour (FULL) intervals for dates between May 1, 2014 and June 16, 2014. The GPM Ground Validation GOES 13 IPHEx data files are in PNG format.

The Global Hydrology Resource Center (GHRC) DAAC published the GPM Ground Validation Upper Air Radiosonde OLYMPEX dataset (

This dataset was collected from October 28, 2015 through January 16, 2016 during the GPM Ground Validation Olympic Mountain Experiment (OLYMPEX) held on the Olympic Peninsula in the Pacific Northwest of the United States. Radiosondes were released from 5 locations: 3 in US - KSLE, KUIL, and NPOL site; and 2 in Canada - ECCC instrument site and CYZT.   A total of 651 radiosondes were launched and collected during OLYMPEX from these sites. In addition, Level 4 dropsonde data were reprocessed to match the Level-4 data format and content of the radiosonde files and is also provided here. The dropsondes were released from the NASA DC-8 aircraft during specific flights in December 2015 and are published as the AVAPS dataset. This Upper Air Radiosonde dataset contains Level 0 through Level 4 data containing dew point temperature, pressure, air temperature, relative humidity, horizontal wind speed, vertical wind speed, wind direction, rise or drop rate, and geopotential height measurements.  The data files are available in ASCII, ASCII-EOL, and netCDF-3 formats, as well as Skew-T and time series plots in PNG format. The lower level datasets (Level 0 raw data through Level 2 data) are only available upon request from the NASA GHRC DAAC.

On Monday, 5/7/2018, Deborah Smith and Tammy Smith of GHRC presented the GHRC data recipes and micro articles, online content available to users that connect information and data. They described the design process used to develop new types of micro articles and the iterative process that occurs between designer and outreach team members.

IFloodS logoGHRC has published the GPM Ground Validation National Mosaic and Multi-Sensor QPE (NMQ) System IFloodS (

This dataset contains quality control products, real time rain rate estimates, hourly precipitation rate estimates, and three-dimensional reflectivity products. These data products are also referred to as Multi-Radar Multi-Sensor Precipitation Reanalysis for Satellite Validation (MRMS) product and were created using the NOAA NMQ System which ingests Weather Surveillance Radar 88 Doppler (WSR-88D) radar data, Rapid Update Cycle (RUC) model analysis fields, and Hydrometeorological Automated Data Systems (HADS) gauge data. The files provided in this dataset are from the NMQ system output obtained during the GPM Iowa Flood Studies (IFloodS) field campaign that occurred throughout Iowa. These data are available in ASCII, netCDF-4, and binary formats for the dates between April 1, 2013 through June 30, 2013.
