  • FY2022 NWS Office of Science and Technology Integration: Unified Forecast System Funding Opportunity

    OSTI is soliciting research proposals that will advance the development of the community-based Unified Forecast System (UFS) through three competitions: 1) Next Generation Global Prediction System (NGGPS); 2) Weeks 3-4/S2S  Program; and 3) Hurricane Forecast Improvement Program (HFIP). This notification (see announcement on grants.gov) is valued at approximately $3,000,000 for the first year of multi-year (2 or 3 year) projects. For more detailed descriptions, please click here.

  • STI-M is pleased to announce the FY2020 NWS Office of Science and Technology Integration: Unified Forecast System Funding Opportunity

    OSTI is soliciting research proposals that will advance the development of the community-based Unified Forecast System (UFS) through three competitions: 1) Next Generation Global Prediction System (NGGPS); 2) Weeks 3-4 Program; and 3) Hurricane Forecast Improvement Program (HFIP). This notification is valued at approximately $2,800,000 for the first year of two-year projects. Universities are encouraged to apply.

NGGPS Overview

The National Oceanic and Atmospheric (NOAA) National Weather Service (NWS) has the responsibility to provide weather, water, and climate information to protect life and property, and enhance the national economy. The NWS mission is to provide the best possible guidance to a wide variety of customers, including emergency managers, forecasters, and the aviation community

The NWS R2O Initiative is expanding and accelerating critical weather forecasting research to operation to address growing service demands, and increase the accuracy of weather forecasts through accelerated development and implementation of current global weather prediction models, improved data assimilation techniques, and improved software architecture and system engineering. The new unified coupled model system will have the flexibility and capability to implement model component improvements as they are developed.

The NWS Research to Operations (R2O) initiative's five year plan is to upgrade the current operational Global Forecast System (GFS) to run as a unified, fully coupled Next Generation Global Prediction System (NGGPS) within NEMS (NOAA Environmental Modeling System) infrastructure. Using advanced high performance computing architectures, the system will incorporate the most recent advances in weather prediction modeling from NOAA and the research community.

  • Implement a weather-scale, fully-coupled NWP System
  • Extend forecast skill beyond 8 to 10 days
  • Improve hurricane track and intensity forecast
  • Extend weather forecasting to 30 days
