GFS (Global Forecast System)Global281616NOAAThe Global Forecast System (GFS), created and maintained by NOAA's National Centers for Environmental Prediction (NCEP), is a weather forecast model that generates data for dozens of atmospheric and land-soil variables, including temperatures, winds, precipitation, soil moisture, and atmospheric ozone concentration. Low resolution but global in scope. Focuses on gradient winds.
5
ECMWF - European Center for Medium Range Weather ForecastsGlobal91016ECMWF (European Union)The ECMWF (European Centre for Medium-Range Weather Forecasts) is a highly-regarded global model. Also referred to as the "Euro Model" or "European Model". Focuses on gradient winds.
6
ICON - Icosahedral NonhydrostaticGlobal13516DWD (German national weather service)The Icosahedral nonhydrostatic model (ICON) is a global model created and operated by the German DWD. Its spatial resolution is higher but its forecast range (time period) is lower than either the GFS or ECMWF.
7
MeteoblueGlobal(variable; "average" of the resolutions of the individual members of the ensemble)7112Meteoblue (private Swiss company)Ensemble of multiple global and regional models assimilated by AI.
8
SPIREGlobal1210112Spire Global (a private-sector, publicly traded corporation)Spire's global model assimilates data, including radio occultation, ocean winds and soil moisture, from its constellation of over 100 satellites.

UKMOGlobal157112United Kingdom Meteorological OfficeThe UKMO global model provides medium-range global forecasts. The model's high-resolution output is particularly useful for capturing local weather phenomena, such as convective showers, coastal effects, and temperature variations across different landscapes.
10
PWGPseudo-Global/ Coastal (see attributes)87112NOAA/PredictWindPredictWind's proprietary extension of the GFS model. Provides forecast information for discrete regions that cover much of the world's coastlines.
11
PWEPseudo-Global/ Coastal (see attributes)87112ECMWF/ PredictWindPredictWind's proprietary extension of the ECMWF model. Provides forecast information for discrete regions that cover much of the world's coastlines.
12
HRRRRegional- Continental US32.2511NOAA/National Center for Environmental PredictionThe HRRR (High Resolution Rapid Refresh) model is a regional model covering the continental United States. This model incorporates real-time weather radar data and can forecast fronts and other convective winds.
13
NAMRegional-Continental US53.516NOAA/National Center for Environmental PredictionThe North American Mesoscale (NAM) forecast system is a regional, mesocale model for North America. Better resolution than global models.
14
PWG 1kmRegional (see attributes)11.5112NOAA/PredictWindPredictWind's proprietary extension of the GFS model. Provides forecast information for widely scattered, discrete regions that focus on the world's most populated coastlines.
15
PWE 1kmRegional (see attributes)11.5112ECMWF/ PredictWindPredictWind's proprietary extension of the ECMWF model. Provides forecast information for widely scattered, discrete regions that focus on the world's most populated coastlines.
