Brief Description:

 NCEP-DOE Reanalysis II (R2) is an improved version of the NCEP-NCAR Reanalysis I (R1). The improvements include an updated model, better physical parameterizations and assorted error fixes. 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 the previous year. A large subset of this data is available from PSD in its original 4 times daily format and as daily averages.

 

Temporal Coverage:

4-times daily values and monthly values for 1979/01/01 to 2014/12/31.

Spatial Coverage:

2.5 degree x 2.5 degree global grids (144x73)
0.0E to 357.5E, 90.0N to 90.0S
