Overview

The HRRR_gf suite is one of the candidates for the future operational implementation of the Rapid Refresh Forecast System (RRFS). Simplified configurations of RRFS can be configured using the UFS SRW App. This suite is similar to the one used by the NOAA operational HRRR v4 (Dowell et al. 2022 [47]), with the addition of the Grell-Freitas deep convective parameterization.

The HRRR_gf suite uses the parameterizations in the following order:
