Climate Reanalysis Data

Climate Wikience provides a sample of variables from several climate reanalysis. Please, refer to the table below.

Name Agency Spatial
resolution
Period
NCEP/NCAR R2 NCEP 2.5° × 2.5° 1979 – current
ERA-Interim ECMWF 1.5° × 1.5° 1979 – current
MERRA NASA 2/3° × 1/2° 1979 – current
20CR NOAA 2.0° × 2.0° 1869 – 2012
CFSR NCEP 0.25° × 0.25° 1979 – 2009

Data are located at the nodes of regular latitude/longitude grid. Temporal resolution is different for each climate reanalysis. Usually it is 6 hours, 3 hours or 1 hour.
