RAPID REFRESH (RAP)/HIGH-RESOLUTION RAPID REFRESH (HRRR)

The Rapid Refresh (RAP) is the continental-scale, hourly-updating, data assimilation and numerical modeling system run operational at the National Centers for Environmental Prediction (NCEP). North American RAP forecasts are complemented by hourly-updating forecasts from the High-Resolution Rapid Refresh (HRRR) model, which are higher resolution and cover smaller geographic domains (CONUS and Alaska).
