    • GPM Ground Validation USDA ARS Soil Moisture IFloodS V1

    Metadata Updated: August 22, 2025

    The GPM Ground Validation United States Department of Agriculture (USDA) Agricultural Research Service (ARS) Soil Moisture IFloodS dataset was collected during the Iowa Flood Studies (IFloodS) ground measurement campaign from April 17, 2013 to June 4, 2013. The goals of the campaign were to collect detailed measurements of precipitation at the Earth’s surface using ground instruments and advanced weather radars and to simultaneously collect data from satellites passing overhead. 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. The data files are available in ASCII-csv and Excel file formats.
