all edu.ucar.gdex GRID GRIB-2 Freely Available CORe is an atmospheric reanalysis from the Climate Prediction Center NCEP/NWS/NOAA with collaboration with Environmental Modeling Center NCEP/NWS/NOAA and Physical Sciences Laboratory NOAA. 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.
