The GHRC DAAC has published two datasets from the Global Precipitation Measurement (GPM) mission Ground Validation (GV) program.
- GPM Ground Validation Micro Rain Radar (MRR) OLYMPEX dataset. This dataset contains measured and derived data from MRR instruments placed in four separate locations within the study region. The MRR is a Biral/Metek 24 GHz (K-band) vertically oriented Frequency Modulated Continuous Wave (FM-CW) radar that measures signal backscatter from which Doppler spectra, radar reflectivity, Doppler velocity, drop size distribution, rain rate, liquid water content, and path integrated attenuation are derived. Data were collected from October 31, 2014 through May 22, 2016, during the Olympic Mountains Experiment (OLYMPEX). DOI: 10.5067/GPMGV/OLYMPEX/MRR/DATA201
- GPM Ground Validation United States Department of Agriculture (USDA) Agricultural Research Service (ARS) Soil Moisture IFloodS dataset. A total of 15 stations were deployed near the South Fork River in North Central Iowa. The soil moisture probes measure hourly instantaneous measurements of the real dielectric permittivity, soil temperature, bulk electrical conductivity, and volumetric soil moisture. This dataset also consists of precipitation amount, air temperature, relative humidity, vapor pressure, wind speed, wind direction, and solar radiation measurements. Data were collected from April 17, 2013 through June 4, 2013, during the Iowa Flood Studies (IFloodS) Field Experiment. DOI: 10.5067/GPMGV/IFLOODS/PROBES/DATA301
