Next Generation Global Prediction System (NGGPS)

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

  • Public Release of the Common Community Physics Package (CCPP)

    The Common Community Physics Package (CCPP) v3.0 was publicly released on June 17, 2019. The CCPP contains a library of physical parameterizations (CCPP-Physics), and the framework that connects it to host models (CCPP-Framework). In this release, the CCPP has been bundled with the Global Model Test bed (GMTB) Single Column Model (SCM) v3.0.
    For access to the code and data, please visit the CCPP website here.
  • NCAR-NOAA Memorandum of Agreement (MOA) for Co-development of a Common Modeling Infrastructure  

    This MOA was signed January 30, 2019. It creates a strategic relationship of mutual benefit for developing the infrastructure to enable broader community engagement for improving the Nation's Earth Modeling System modeling capabilities for operational and research applications. You can access the MOA at this link.
  • The FY19-FY21 Strategic Implementation Plan  

    Building on the accomplishments and momentum of efforts over the past year, the first annual update to the Strategic Implementation Plan (SIP) for the Evolution of NGGPS to a National Unified Modeling System, the Unified Forecast System (UFS), is available.  The link is here.
    The Unified Forecast System (UFS) is envisioned to be a community-based, coupled comprehensive Earth system modeling system,designed to support the Weather Enterprise and to be the source system for NOAA's operational numerical weather prediction applications, as well as to serve both the Research & Development, and Operational communities engaged in the numerical prediction of the Earth System. This document is the UFS Strategic Implementation Plan (SIP) for FY 2019 - 2021. It is the first annual update to the initial SIP and describes the actions required of community participants in the next one to three years as they work together to evolve the UFS.
