    • GPM GROUND VALIDATION MICRO RAIN RADAR (MRR) NASA IFLOODS V1

    Metadata Updated: April 10, 2026

    The GPM Ground Validation Micro Rain Radar (MRR) NASA IFloodS dataset was collected by a Micro Rain Radar (MRR), which is a vertically pointing Doppler radar which provided measurements of vertical velocity, drop size distribution, rainfall rate, attenuation, liquid water content, and reflectivity factor during the Iowa Flood Study (IFloodS), which took place in eastern Iowa during the spring of 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, simultaneously, collect data from satellites passing overhead. A total of four MRRs were deployed, each adjacent to a two-dimensional video disdrometer (2DVD). Each MRR-2DVD site had one or more Autonomous Parsivel2 Unit (APU) with tipping bucket rain gauges either collocated or within 4-8 km away. The dataset covers the period of April 11, 2013 through June 16, 2013, but each MRR deployed may not contain data during the entirety of this period.
