CORe is designed to replace CDAS (real-time extension to NCEP/NCAR Reanalysis - d090000 on GDEX). CORe covers a similar period of time (1950 to real time compare to 1948 to real time), and was designed for climate monitoring, one of the Climate Prediction Center's major goals. Unlike most modern reanalyses, CORe does not assimilate satellite data except for Atmospheric Motion Vectors (AMV). This was done to eliminate spurious "climate shifts" caused by the ingest of satellite data. This problem affected the earlier NCEP/NCAR and Climate Forecast System Reanalyses. This design emphasizes improving the climate trends and anomalies over getting the best state for a forecast. 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 REANALYSIS MODELS 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 EARTH SCIENCE > ATMOSPHERE > ALTITUDE > GEOPOTENTIAL HEIGHT EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PRESSURE > AIR MASS/DENSITY EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC TEMPERATURE > SURFACE TEMPERATURE > AIR TEMPERATURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC TEMPERATURE > UPPER AIR TEMPERATURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WINDS > SURFACE WINDS EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WINDS > UPPER LEVEL WINDS EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WINDS > UPPER LEVEL WINDS > BOUNDARY LAYER WINDS EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WINDS > WIND DYNAMICS 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 0.703 eng utf-8 climatologyMeteorologyAtmosphere -180.0 180.0 -89.463 89.463 1950-02-13T1200+00 2026-04-07T0300+00 NSF NCAR Geoscience Data Exchange datahelp@ucar.edu https://gdex.ucar.edu distributor 1796146.295 https://gdex.ucar.edu/datasets/d090004/ https Dataset Description Related Link information https://gdex.ucar.edu/datasets/d090004/dataaccess/ https Data Access Related Link download none asNeeded
