NCEP-DOE AMIP-II Reanalysis

The NCEP-DOE Reanalysis 2 project is using a state-of-the-art analysis/forecast system to perform data assimilation using past data from 1979 through near present. Data is output on 17 pressure levels and on single level grids. Data is output 4x daily and is also available as daily and monthly. Climatologies are provided for select variables.
