GPM GV Radar Data

The Global Precipitation Measurement Mission (GPM) Ground Validation (GV) program ingests radar data from approximately 90 sites. The data is first quality controlled then processed to add rain rate, hydro-meteor identification, median volume diameter, and normalized intercept parameter.

GPM GV Data Specifics

  • Radar data from 59 sites are quality controlled (QC) at satellite overpass times for the GPM Validation Network.
  • Data are available in UF format.
  • Complete QC radar datasets (24/7) are available from 4 sites:
    • KMLB: Melbourne, FL
    • KPOL: Kwajalein Atoll, RMI; Data are calibration adjusted.
    • KDOX: Dover, DE
    • KAKQ: Wakefield, VA
  • NPOL data are available from Newark, MD and from GPM-GV field campaigns.
    • Newark, MD: QC and calibrated data available on event-to-event basis.
      • View NPOL event calendar for:
