LOIs are strongly encouraged (but not required) and must be received by email by 5:00 PM Eastern Time (ET) on December 6, 2021.
Full application packages for all competitions must be submitted via Grants.gov no later than 5:00 PM Eastern Time (ET) on February 7, 2022. 

NOAA’s National Weather Service (NWS) Office of Science and Technology Integration (OSTI) Modeling Program Division is soliciting research proposals to support NOAA’s development of the community-based and comprehensive coupled modeling system, the Unified Forecast System (UFS). The UFS is designed to provide more accurate forecast guidance through operational numerical weather prediction applications. These applications span local and global domains, and predictive time scales from sub-hourly to seasonal (S2S).

There are three competitions from this notification valued at approximately $3,000,000 for the first year of multi-year (2 or 3 year) projects that will advance development of the UFS: 1) Next Generation Global Prediction System (NGGPS); 2) Weeks 3-4/S2S Program; and 3) Hurricane Forecast Improvement Program (HFIP).

Research projects to advance NGGPS will propose accelerating improvement of operational global weather prediction models; coupling among atmosphere, ocean, waves, ice, land and atmospheric composition systems; improving data assimilation techniques; improving physical parameterization schemes; improving ensemble techniques; developing post-processing forecast tools and techniques; or improving software architecture, computational performance and system engineering.
