The Global Forecast System (GFS) is a weather forecast model produced
by the National Centers for Environmental Prediction (NCEP). Dozens of
atmospheric and land-soil variables are available through this dataset,
from temperatures, winds, and precipitation to soil moisture and
atmospheric ozone concentration. The entire globe is covered by the GFS
at a base horizontal resolution of 18 miles (28 kilometers) between grid
points, which is used by the operational forecasters who predict weather
out to 16 days in the future. Horizontal resolution drops to 44 miles
(70 kilometers) between grid point for forecasts between one week and two
weeks.

NOTE - Upgrade NCEP Global Forecast System to v16.3.0 - Effective November 29, 2022 See notification HERE
The Global Forecast System (GFS) is a weather forecast model produced
by the National Centers for Environmental Prediction (NCEP). Dozens of
atmospheric and land-soil variables are available through this dataset,
from temperatures, winds, and precipitation to soil moisture and
atmospheric ozone concentration. The entire globe is covered by the GFS
at a base horizontal resolution of 18 miles (28 kilometers) between grid
points, which is used by the operational forecasters who predict weather
out to 16 days in the future. Horizontal resolution drops to 44 miles
(70 kilometers) between grid point for forecasts between one week and two
weeks.
The NOAA Global Forecast Systems (GFS) Warm Start Initial Conditions are
produced by the National Centers for Environmental Prediction Center (NCEP)
to run operational deterministic medium-range numerical weather predictions.
The GFS is built with the GFDL Finite-Volume Cubed-Sphere Dynamical Core (FV3)
and the Grid-Point Statistical Interpolation (GSI) data assimilation system.
Please visit the links below in the Documentation section to find more details
about the model and the data assimilation systems. The current operational
GFS is run at 64 layers in the vertical extending from the surface to the upper
stratosphere and on six cubic-sphere tiles at the C768 or 13-km horizontal
resolution. A new version of the GFS that has 127 layers extending to the
mesopause will be implemented for operation on February 3, 2021. These initial
conditions are made available four times per day for running forecasts at the
00Z, 06Z, 12Z and 18Z cycles, respectively. For each cycle, the dataset
contains the first guess of the atmosphere states found in the directory
./gdas.yyyymmdd/hh-6/RESTART, which are 6-hour GDAS forecast from the last
cycle, and atmospheric analysis increments and surface analysis for the current
cycle found in the directory ./gfs.yyyymmdd/hh, which are produced by the data
assimilation systems.

The Global Forecast System (GFS) is a weather forecast model produced by the National Centers for Environmental Prediction (NCEP). Dozens of atmospheric and land-soil variables are available through this dataset, from temperatures, winds, and precipitation to soil moisture and atmospheric ozone concentration. The GFS data files stored here can be immediately used for OAR/ARL’s NOAA-EPA Atmosphere-Chemistry Coupler Cloud (NACC-Cloud) tool, and are in a Network Common Data Form (netCDF), which is a very common format used across the scientific community. These particular GFS files contain a comprehensive number of global atmosphere/land variables at a relatively high spatiotemporal resolution (approximately 13x13 km horizontal, vertical resolution of 127 levels, and hourly), are not only necessary for the NACC-Cloud tool to adequately drive community air quality applications (e.[...]
The Global Forecast System (GFS) is a National Oceanic and Atmospheric
Administration (NOAA) National Centers for Environmental Prediction
(NCEP) weather forecast model that generates data for dozens of
atmospheric and land-soil variables, including temperatures, winds,
precipitation, soil moisture, and atmospheric ozone concentration. The
system couples four separate models (atmosphere, ocean model, land/soil
model, and sea ice) that work together to depict weather conditions.
These datasets have been translated to cloud-optimized Icechunk Zarr format by dynamical.org.
When Icechunk 2.0 is released, these datasets will be updated correspondingly, and updated client libraries will be required for access. To be notified of dataset updates, subscribe to the mailing list.

The Unified Forecast System (UFS) is a community-based, coupled, comprehensive Earth Modeling System. It supports multiple applications with different forecast durations and spatial domains. The Global Data Assimilation System (GDAS) Application (App) is being used as the basis for uniting the Global Workflow and Global Forecast System (GFS) model with Joint Effort for Data assimilation Integration (JEDI) capabilities.
The National Centers for Environmental Prediction (NCEP) use GDAS to interpolate data from various observing systems and instruments onto a three-dimensional grid. GDAS obtains its data through several observation types: surface, balloon, wind profilers, aircraft reports, buoys, radar, and satellite. This gridded out[...]
The Servicio Meteorológico Nacional de Argentina (SMN-Arg), the National Meteorological Service of Argentina, shares its deterministic forecasts generated with WRF 4.0 (Weather and Research Forecasting) initialized at 00 and 12 UTC every day.
This forecast includes some key hourly surface variables –2 m temperature, 2 m relative humidity, 10 m wind magnitude and direction, and precipitation–, along with other daily variables, minimum and maximum temperature.
The forecast covers Argentina, Chile, Uruguay, Paraguay and parts of Bolivia and Brazil in a Lambert conformal projection, with 4 km horizontal resolution. The maximum lead time is 72 hours.
Forecasts are initialized with the NCEP-NOAA Global Forecast Systems analysis and forecasts (GFS).
