Listed in National Center for Atmospheric Research
The North American Mesoscale Forecast System (NAM) is one of the National Centers For Environmental Prediction's (NCEP) major models for producing weather forecasts.
Description
NAM generates multiple grids (or domains) of weather forecasts over the North American continent at various horizontal resolutions. Each grid contains data for dozens of weather parameters, including temperature, precipitation, etc.
The analysis output archived here is over continental United States at 12 km spatial resolution every 6 hours.
