NCEP Reanalysis Tropopause LevelEntry ID: noaa_cdc030
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
