The GFS is run four times a day, and produces forecasts for up to 16 days in advance. The forecast component uses the FV3 model with a resolution of ~13 km. In the vertical, the model is divided into 64 layers and temporally, it produces forecast output every hour for the first 120 hours, then every 3 hours for days 5-16. Details on the June 2019 implementation of the FV3 version of the GFS. June 12, 2019 NOAA's flagship weather model — the Global Forecast System (GFS) — is undergoing a significant upgrade today to include a new dynamical core called the Finite-Volume Cubed-Sphere (FV3). This upgrade will drive global numerical weather prediction into the future with improved forecasts of severe weather, winter storms, and tropical cyclone intensity and track

The Global Data Assimilation System (GDAS) is the system used by the National Center for Environmental Prediction (NCEP) Global Forecast System (GFS) model to place observations into a gridded model space for the purpose of starting, or initializing, weather forecasts with observed data. GDAS adds the following types of observations to a gridded, 3-D, model space: surface observations, balloon.

This mathematical model is run four times a day. It is an excellent model in the one- to five-day range. The accuracy drops significantly after day five, and significant long-range forecast changes are noted from run to run. The graphics above show the barometric pressure field. Lower pressures.

May 11, 2016 NOAA's powerful new supercomputers paved the way for another upgrade to the U.S. Global Forecast System (GFS), NOAA's primary model for weather prediction. Today's upgrade builds on last year's significant boost to the GFS, which more than doubled the resolution of the model grid from 27 kilometers to 13 kilometers, resulting in higher resolution model output and more. NOAA's National Weather Service Environmental Modeling Center is responsible for the GFS model. As of the time this article was written (July 2018) the most recent update to GFS was July 19, 2017, when version v14 of GFS was put into production. There has been a continual series of improvements to the GFS, roughly once per year Note to users: MOS products are no longer being developed as stand-alone products, and we are considering gradually phasing them out in the next couple of years (this does not include LAMP and GLMP products)
