Global weather forecast model via Unidata (NOAA GFS)
What it measures. The same worldwide weather forecast as the main GFS, covering dozens of variables such as temperature, winds, precipitation, soil moisture, and atmospheric ozone, mapped across the whole globe at about 18-mile resolution.
How it's made. This is a copy of NOAA's Global Forecast System model output, distributed through the Unidata community for easier access.
How & where you'd use it. Drives weather prediction out to roughly 16 days and feeds research, education, and applications in farming and emergency response.

Official description
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.
