The Unified Forecast System weather model is the community-based coupled earth science modeling system. Through the collaboration of NOAA laboratories and the broad research community, the coupling infrastructure has been developed with new model components integrated into the system and the coupling capability set up to support various configurations. Currently the UFS coupled model consists of FV3 dynamical core with the Common Community Physics Package (CCPP) for the atmosphere, MOM6 and HYCOM for the ocean, CICE6 for sea ice, WW3 for ocean waves, NoahMP for land, GOCART and CMAQ for aerosol and chemistry and the Community Mediator for Earth Prediction Systems (CMEPS) based on ESMF NUOPC for coupling framework. The UFS weather model supports the Hurricane Analysis and Forecast System (HAFS) v1, Regional Air Quality Model (AQM)v7, and upcoming Rapid Refresh Forecast System (RRFS) v1, Global Forecast System (GFSv17) and Global Ensemble Forecast System (GEFSv13) implementations.
In this presentation, an overview of general model infrastructure for the UFS coupled model will be provided. Major infrastructure achievements will be presented. New approaches that were implemented to improve the computational performance will also be discussed.
Jun Wang has been at the Environmental Modeling Center since 2002 working on numerical modeling and system architecture development. She developed the atmosphere ocean coupler for NCEP’s Climate Forecast Model version 2 and later worked on various earth modeling systems including Global Forecast Model, whole atmosphere space weather model, and global aerosol models and UFS. Currently she is the team lead and member developing the UFS weather model infrastructure to support operational implementations and the research community.
