FV3 has been chosen as the dynamical core for the Next Generation Global Prediction System project (NGGPS), designed to upgrade the current operational Global Forecast System (GFS) to run as a unified, fully-coupled system in NOAA’s Environmental Modeling System infrastructure. FV3 was successfully implemented within the GFS, and the FV3-based GFSv15 became operational on 12 June 2019. Other applications, such as regional high-resolution forecasting and coupled atmosphere-ocean modeling for seasonal prediction, are planned for later implementation at NCEP.
