Three Summer Meetings to Support the Advancement of the United Forecast System and R2O  

Continuing on the success and forward momentum of the early January SIP meeting, three workshops/meetings will occur late July, early August 2018

  • Test Plans and Metric Workshop: July 30 - August 1, 2018
  • SIP Annual Meeting: August 1 - August 3, 2018
  • NGGPS Principal Investigators (PI) Meeting: August 13 - 14, 2018

NGGPS is evolving into a unified forecast system through a Strategic Implementation Plan (SIP)

The overall goal to create a multi-year Strategic Implementation Plan (SIP) to document the effort of the community as the NGGPS moves towards a unified forecast system is described on the NGGPS Implementation page.


EMC Implementation Plan (IP) for FY 2018 - FY 2020

The EMC Implementation Plan (IP) 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.


Round 3 of Research to Operations Initiative: NGGPS and HFIP 

NOAA-NWS-NWSPO-2018-2005325 is closed

NOAA is reviewing the proposals.  Information can be found on the page.

Full proposals were due February 7, 2018

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 will expand and accelerate 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
