Dataset Format and Size

Missing Data

  • Missing data is flagged with a value of -9.96921e+36f.

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. A large subset of this data is available from PSL in its original 4 times daily format and as daily and monthly averages.

It is very similar to the NCEP/NCAR Reanalysis and fixes some assimilation issues in theNCEP Reanalysis

Usage Restrictions

  • None

Caveats

  • None.
