The final version of 15 km horizontal resolution data set which spans 2000-2016 is available on line through the NCAR's RDA. Similar to ASR version 1, ASR version 2 has 34 pressure levels (71 model levels), 31 surface (including 3 soil variables) and 11 upper air analysis variables, 71 surface (including 3 soil variables) and 17 upper air forecast variables. Both the u- and v- winds relative to grid and relative to earth are present in the final version. The wind speed is also added. ASR version 2 will be updated through 2019, then reran (2000-2019) using the most recent version of Polar WRF and WRFDA plus many other enhancements. This newer version, ASR version 2.5, should be available starting in mid-2020 and will be kept up-to-date through 2020 with a delay of about 3 months. completed datahelp@ucar.edu pointOfContact notPlanned dataset https://gdex.ucar.edu/images/ds_logos/default_200_200.png Logo thumbnail from URL png NetCDF4 dataset Resource Type 2021-03-30 revision 4.4 DataCite Metadata Working Group orginator resourceTypeGeneral MODELS > MODELS REANALYSIS MODELS U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-08-19 revision 24.6 NASA Global Change Master Directory orginator Valids List: Platforms ASR > BPRC Arctic System Reanalysis U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-08-19 revision 24.6 NASA Global Change Master Directory orginator Valids List: Projects EARTH SCIENCE > ATMOSPHERE > ALTITUDE > GEOPOTENTIAL HEIGHT EARTH SCIENCE > ATMOSPHERE > ALTITUDE > PLANETARY BOUNDARY LAYER HEIGHT EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PRESSURE > SEA LEVEL PRESSURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PRESSURE > SURFACE PRESSURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC RADIATION > HEAT FLUX EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC RADIATION > LONGWAVE RADIATION EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC RADIATION > OUTGOING LONGWAVE RADIATION EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC RADIATION > SHORTWAVE RADIATION EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC TEMPERATURE > SURFACE TEMPERATURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC TEMPERATURE > SURFACE TEMPERATURE > AIR TEMPERATURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WATER VAPOR > WATER VAPOR INDICATORS > HUMIDITY EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WINDS > SURFACE WINDS EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WINDS > WIND DYNAMICS > VERTICAL WIND VELOCITY/SPEED EARTH SCIENCE > ATMOSPHERE > CLOUDS > CLOUD PROPERTIES > CLOUD FRACTION EARTH SCIENCE > ATMOSPHERE > PRECIPITATION > PRECIPITATION AMOUNT EARTH SCIENCE > BIOSPHERE > VEGETATION > CANOPY CHARACTERISTICS EARTH SCIENCE > LAND SURFACE > LAND USE/LAND COVER > LAND USE/LAND COVER CLASSIFICATION EARTH SCIENCE > LAND SURFACE > SOILS > SOIL CLASSIFICATION EARTH SCIENCE > LAND SURFACE > SOILS > SOIL MOISTURE/WATER CONTENT EARTH SCIENCE > LAND SURFACE > SOILS > SOIL TEMPERATURE EARTH SCIENCE > LAND SURFACE > SURFACE RADIATIVE PROPERTIES > ALBEDO EARTH SCIENCE > LAND SURFACE > SURFACE RADIATIVE PROPERTIES > EMISSIVITY EARTH SCIENCE > LAND SURFACE > SURFACE THERMAL PROPERTIES > SKIN TEMPERATURE EARTH SCIENCE > OCEANS > OCEAN TEMPERATURE > SEA SURFACE TEMPERATURE EARTH SCIENCE > OCEANS > SEA ICE > ICE DEPTH/THICKNESS EARTH SCIENCE > OCEANS > SEA ICE > SEA ICE CONCENTRATION EARTH SCIENCE > TERRESTRIAL HYDROSPHERE > SNOW/ICE > ALBEDO EARTH SCIENCE > TERRESTRIAL HYDROSPHERE > SNOW/ICE > SNOW COVER EARTH SCIENCE > TERRESTRIAL HYDROSPHERE > SNOW/ICE > SNOW DEPTH EARTH SCIENCE > TERRESTRIAL HYDROSPHERE > SNOW/ICE > SNOW WATER EQUIVALENT EARTH SCIENCE > TERRESTRIAL HYDROSPHERE > SURFACE WATER > SURFACE WATER PROCESSES/MEASUREMENTS > RUNOFF U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-08-19 revision 24.6 NASA Global Change Master Directory orginator Valids List: Science and Services Keywords Creative Commons Attribution 4.0 International License None grid 15000.0 eng utf-8 climatologyMeteorologyAtmosphere 0.0005745393972063084 -0.0016643312958990464 24.643289708511624 89.89776726397238 2000-01-01T0000+00 2016-12-31T2100+00 NSF NCAR Geoscience Data Exchange datahelp@ucar.edu https://gdex.ucar.edu distributor 53091279.133 https://gdex.ucar.edu/datasets/d631001/ https Dataset Description Related Link information https://gdex.ucar.edu/datasets/d631001/dataaccess/ https Data Access Related Link download none asNeeded
