NGGPS Modeling Community, including FV3

NOAA NGGPS FV3-based Unified Modeling System: Vision for Community

The FV3GFS official evaluation is underway. There is a lot of good information about the model and implementation timeline, as well as links to get data, see stats, and view forecast images on the FV3GFS official evaluation website.
Pending a successful validation, the preliminary timeline calls for the FV3GFS to replace the operational GFS at the end of the calendar year. The purpose of this upgrade is to confirm that the FV3 core can successfully replace the spectral model core in operations. The Zhao-Carr microphysics are being replaced by the GFDL microphysics in the FV3GFS, but most of the GFS physics will be retained in this package. Getting the FV3 core into operations will pave the way for a GFS upgrade in 2020 that will feature advanced physics and higher resolution. This is a major initial step in the unification (and eventual simplification) of the NCEP Production Suite around the FV3 core.
The numerical weather prediction community, including NOAA, Navy, National Aeronautics Space Administration (NASA), and other federal agency laboratories and Universities, are contributing to the Next Generation Global Prediction System (NGGPS).  NGGPS is now evolving into a National Unified Modeling System guided by the Strategic Implementation Plan (SIP).   The SIP document can be found here.  
EMC's implementation plan (IP) for FY 2018 - FY 2020 is released. This Implementation Plan describes the major development and implementation projects planned for EMC over this time frame, and how those fit within the broader NOAA Strategic Vision and Roadmap for modeling (under development), as well as how EMC projects link with other model-related projects internally within NOAA and with the broader U.S. modeling community, including the Strategic Implementation Plan (SIP) to the Next Generation Global Prediction System.
Information on the many partners and collaborating organizations involved in the development of NGGPS can be found on the Community Partners page.

How to get involved

NOAA seeks to engage with the public, private, and academic sectors to develop and advance a world-class operational modeling system that is unified across time and space scales.  

Get involved in the Strategic Implementation Plan (SIP) Working Groups


The SIP Working Groups are always seeking members from the research and development community. To inquire, please contact Steve Warren, NGGPS Program Office, 

Participate in the Community Workshops:


NGGPS/SIP Annual Meeting August 1 - 3, 2018

The next NGGPS/SIP meeting is scheduled to start after noon on August 1 and continue through Friday August 3, 2018. Further information will be posted when available. Those within the community who would like to learn more about the SIP plan for the next year are welcome to attend.


Successful NOAA Community Modeling Workshop & Strategic Implementation Plan (SIP) Coordination Workshop in College Park, MD (April 18-20, 2017)

NOAA engaged with over 170 participants from the public, private, and academic sectors to help NOAA plan and establish the NOAA Modeling Community. The workshop took place at the NOAA Center for Weather and Climate Prediction (NCWCP) in College Park, MD. The workshop refined NOAA's vision for the weather model development community, examined priorities on system development and how it impacts the schedule, discussed how the community will be engaged in the process, and how community-based unified modeling will work. Through the workshop goals, NOAA:

  • Refined the community vision
  • Discussed how the community will be engaged in the process
  • How community-based unified modeling will work, including governance, code repositories, testing and evaluation, etc.
  • Determined priorities on system development and how it impacts the schedule

For further information, please click on the Meeting page Presentations and outcome of the discussions will be posted soon.

Participate in NGGPS call for proposals


The NGGPS Program Office Federal Funding Opportunity (FFO) for a Summer 2018 award is closed. 

Round 3 of Research to Operations Initiative: NGGPS and HFIP (NOAA-NWS-NWSPO-2018-2005325) and Round 3 of Research to Operations Initiative: NOAA Testbeds (NOAA-NWS-NWSPO-2018-2005317) are now closed. Full proposals were due February 7, 2018.  More formation can be found on the page.

NGGPS Funded Projects

As a community modeling effort, over $12M has been awarded to university and Federal PI's, fostering collaboration between universities, internal weather testbeds and Federal laboratories. Specific details can be found on the NGGPS Funded Projects page. 


A list of all STI funded projects, including those funded by NGGPS, can be found at Current STI Grants and Projects.
