High-Resolution Rapid Refresh (HRRR)

GribStream Code: hrrr

Description

HRRR (High-Resolution Rapid Refresh) is NOAA/NCEP’s real-time, convection-allowing model for the contiguous United States. It couples a WRF-ARW forecast core with a rapid data-assimilation cycle that ingests surface and mesonet stations, radiosondes, aircraft reports, satellite winds, and MRMS radar reflectivity at high frequency. The system is tuned for mesoscale and boundary-layer phenomena, capturing thunderstorm initiation and evolution, low clouds and fog, snow bands, gap winds, and smoke dispersion. HRRR guidance is a key short-range input to the NBM and has informed the development of the RRFS.
