The Global Forecast System GFS is a 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. Grids, domains, run frequencies, and output frequencies have changed over the years. The model is constantly evolving, and regularly adjusted to improve performance and forecast accuracy. GFS is a global model with a base horizontal resolution of 18 miles 28 kilometers between grid points.

We have forecast data from several regional models that cover United States. These models have a higher resolution than global models that forecast for the whole world, but the increased computational demands of a high resolution model mean that these forecasts only go a couple days out in time, and are limited to a small area. We have forecast data from a variety of global models that produce forecasts for the whole world, up to two weeks out in time. Weather models, known formally as "Numerical Weather Prediction" are at the core of modern weather forecasts. All the forecast information you see at weather. Weather models are simulations of the future state of the atmosphere out through time. Millions of observations are used as initial conditions in trillions of calculations, producing a three dimensional picture of what the atmosphere might look like at some time in the future. Massive computers are used to do these calculations at incredibly fast speeds to enable simulations to cover the entire globe, and extend up to two weeks into the future. There are two general types of weather models, global models and regional models. Global models produce forecast output for the whole globe, generally extending a week or two into the future.

GFS is a global model with a base horizontal resolution of 18 miles 28 kilometers between grid points. Temporal resolution covers analysis and forecasts out to 16 days. Horizontal resolution drops to 44 miles 70 kilometers between grid points for forecasts between one week and two weeks. Data on Cloud Servers.
