Summary

Abstract:
The NCEP/NCAR Reanalysis project is using a state-of-the-art analysis/forecast system to perform data assimilation using past data from 1948 to the present. A large subset of this data is available from CDC in its original 4 times daily format and as daily averages. However, the data from 1948-1957 is a little different, in the regular (non-Gaussian) gridded data. That data was done at 8 times daily in the model, because the inputs available in that era were available at 3Z, 9Z, 15Z, and 21Z, whereas the 4x daily data has been available at 0Z, 6Z, 12Z, and 18Z. These latter times were forecasted and the combined result for this early era is 8x daily. The local ingestion process took only the 0Z, 6Z, 12Z, and 18Z forecasted values, and thus only those were used to make the daily time series and monthly means here. Please read the problem list before using the data. The NCEP/NCAR Reanalysis descriptions here are subdivided into separate data sets These are currently: Pressure Level Data Surface Data Surface Flux Data Other Flux Data Tropopause Level Data T62 Spectral Coefficients You can now search the NCEP/NCAR Reanalysis data by selecting one of these links: Search all of the NCEP/NCAR Reanalysis available at CDC.
