NCEP-DOE Reanalysis 2, Monthly

Monthly means from 6-hourly values: Gaussian Grid

The NCEP/DOE AMIP-II Reanalysis (Reanalysis-2) is based on the widely used NCEP/NCAR Reanalysis. NCEP-DOE Reanalysis 2 is an improved version of the NCEP Reanalysis I model that fixed errors and updated parameterizations of physical processes. It is using a state-of-the-art analysis/forecast system to perform data assimilation using past data from 1979 through the previous year. A large subset of this data is available from the Physical Sciences Division (PSD) at NOAA in its original 4 times daily format and as daily averages.
