Derived / Other Model Data
Sea Surface Temperature (SST) and Winds
Several SST and ocean wind datasets, from different satellites, are available through NOMADS, each with a different period of record.
Service Records Retention System (SRRS)
SRRS is a store of weather observations, summaries, forecasts, warnings, and advisories generated by the U.S. National Weather Service (NWS) for public use.
NOMADS Ensemble Probability Tool
The NOMADS Ensemble Probability Tool allows a user to query the Global Ensemble Forecast System (GEFS) to determine the probability that a set of forecast conditions will occur at a given location using all of the 21 separate GEFS ensemble members.
National Digital Forecast Database (NDFD)
NDFD are gridded forecasts created from weather data collected by NWS field offices and processed through the National Centers for Environmental Prediction. NDFD data are accessed by World Meteorological Organization header or by date range.
National Digital Guidance Database (NDGD)
NDGD consists of forecasts, observations, model probabilities, climatological normals, and other digital data that complement the NDFD.
