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.
