Published by NASA/MSFC/GHRC | National Aeronautics and Space Administration | Catalog Last Checked: September 22, 2026 at 11:37 PM | Dataset Last Updated: September 22, 2026
The Passive Microwave Hail Climatology Data Products are gridded estimates of the annual frequency of severe hailstorm occurrence, as retrieved from satellite-borne passive microwave imagery. These data products can be useful for weather and climatological research related to storms, as well as applications involving risk management and emergency management. The dataset files are available in netCDF-3 format, as well as hail climatology maps in PNG format, from January 1, 1998, through March 31, 2026. NOTE: The TRMM_HailClimatology file only goes through September 30, 2014 due to the end of the TRMM mission.
