NCAR Reanalysis 1 Summary One Line Description NCEP NCAR Reanalysis 1 Temporal Coverage 4 times daily daily and monthly values for 1948 01 01 to present Long term monthly means derived from data for years 1968 1996 Spatial Coverage Global Grids Levels 17 Pressure level and 28 sigma levels N A Update Schedule Daily We have separated the data documentation into seven sections Pressure level Surface Surface Fluxes Other Fluxes Tropopause Derived Data Spectral Coefficients Usage Restrictions None Detailed Description The NCEP NCAR Reanalysis 1 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 PSD 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 Caveats Please read the problem list before using the data Related File
