RRFS_v1beta Suite

Overview

The RRFS_v1beta suite is one of the candidates for the future operational implementation of the Rapid Refresh Forecast System (RRFS), which can be configured using the UFS SRW App. This suite is most applicable for runs at 3-km resolution since it does not parameterize deep convection.

The RRFS_v1beta suite uses the parameterizations in the following order:

• Subgrid-scale Cloud Interstitial
• GFS RRTMG Shortwave/Longwave Radiation Scheme
• MYNN Surface Layer Scheme
• GFS Near-Surface Sea Temperature Scheme
• GFS NoahMP Land Surface Model
• GFS Sea Ice Scheme
• MYNN-EDMF Boundary Layer and Shallow Cloud Scheme
• Unified Gravity Wave Physics Scheme - Version 0
• GFS Ozone Photochemistry (2015) Scheme
• GFS Stratospheric H2O Scheme
• Thompson Aerosol-Aware Cloud Microphysics Scheme
