Unified Forecast System (UFS) Noah-MP Land Data Assimilation Release and Community Support

The Unified Forecast System (UFS) Weather Model (WM) is a community-based, coupled, comprehensive Earth modeling system used for short- and medium-range research and operational forecasts including the NOAA operational Global Forecast System (GFS). Based on the UFS coupling options through the Community Data Models for Earth Prediction Systems (CDEPS) and the active atmosphere model through the Community Mediator for Earth Prediction Systems (CMEPS), the community land surface model Noah-Multi-Physics (MP) as a component model can be configured to run in one-way coupled mode with atmospheric forcings or in two-way mode, coupled to the active atmosphere model. The Earth Prediction Innovation Center (EPIC) and the UFS community have released the stand-alone versions of the Noah-MP Land Data Assimilation (DA) System in the UFS infrastructure framework. The releases reflect the integration of the UFS-WM Noah-MP land surface model component with the Joint Effort for Data assimilation Integration (JEDI) system for the assimilation of snow depth observations provided from the Global Historical Climatology Network - Daily (GHCN-Daily) dataset. In this presentation, we review the latest release features, community support strategies, and code integration infrastructure options.
