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. onGoing datahelp@ucar.edu pointOfContact daily dataset https://gdex.ucar.edu/images/ds_logos/default_200_200.png Logo thumbnail from URL png WMO GRIB2 dataset Resource Type 2021-03-30 revision 4.4 DataCite Metadata Working Group orginator resourceTypeGeneral NCEP-NAM > NCEP North American Model U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-03-19 revision 23.6 NASA Global Change Master Directory orginator Valids List: Platforms WRF > WRF (Weather Research and Forecasting) Modeling U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-03-19 revision 23.6 NASA Global Change Master Directory orginator Valids List: Projects EARTH SCIENCE > ATMOSPHERE > ALTITUDE > GEOPOTENTIAL HEIGHT EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PRESSURE > SEA LEVEL PRESSURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PRESSURE > SURFACE PRESSURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC TEMPERATURE > SURFACE TEMPERATURE > AIR TEMPERATURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC TEMPERATURE > UPPER AIR TEMPERATURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WATER VAPOR > WATER VAPOR INDICATORS > HUMIDITY EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WINDS > UPPER LEVEL WINDS EARTH SCIENCE > ATMOSPHERE > PRECIPITATION > SOLID PRECIPITATION > SNOW U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-03-19 revision 23.6 NASA Global Change Master Directory orginator Valids List: Science and Services Keywords Creative Commons Attribution 4.0 International License None grid 12191.0 eng utf-8 climatologyMeteorologyAtmosphere -152.8787528266125 -49.415436537703386 12.18999999999998 61.309523510494856 2012-01-01T0000+00 2026-04-03T0600+00 NSF NCAR Geoscience Data Exchange datahelp@ucar.edu https://gdex.ucar.edu distributor 916278.477 https://gdex.ucar.edu/datasets/d609000/ https Dataset Description Related Link information https://gdex.ucar.edu/datasets/d609000/dataaccess/ https Data Access Related Link download none asNeeded
