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

    Metadata Updated: April 10, 2026

    The GPM Ground Validation NASA Micro Rain Radar (MRR) is a vertically pointing Doppler radar which provided measurements of vertical velocity, drop size distribution, rainfall rate, attenuation, liquid water content, and reflectivity factor obtained during the Integrated Precipitation and Hydrology Experiment (IPHEx), which took place in western North Carolina during the spring of 2014. A total of four MRRs were deployed, some co-located with other instruments and some were moved to different locations during the campaign. The dataset covers the period of April 22, 2014 through June 16, 2014, but each MRR deployed may not contain data during the entirety of this period. Two MRRs remained deployed through October 17, 2014 and data from these are also included in this dataset.
