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 subset of this data has been processed to
create monthly means of a subset of the original data. There are also
files containing data from variables derived from the reanalysis and
some other statistics. Information about the 4 times and daily data is
available, as well. Please read the problem list before using the
data. The NCEP/NCAR Reanalysis descriptions here are subdivided into
separate categories. These are currently: Pressure Level Data Surface
Data Surface Flux Data Other Flux Data Tropopause Level Data Sigma
Level Data If you don't know where to find a variable, you can search
this table. All the files are in netcdf format and are located in the
directories that follow the naming convention:
/Datasets/ncep.reanalysis.derived/subdirectory_name/ where
subdirectory_name is Categorysubdirectory_name Pressure levelpressure
Surfacesurface Surface Fluxsurface_gauss Other Fluxother_gauss
Tropopausetropopause Sigma Levelspectral The naming convention of the
files is generally variable.averagingperiod.statistic.nc where
variable is netcdf variable name averagingperiod is time period over
which data is averaged (day,mon) statistic is type of data (mean,
long-term mean(ltm), etc) Some files have the level included with the
variable names e.g. air2m.mon.mean.nc Here the file should be read
with the variable of 'air' Information is available on the time period
of the files and how the different statistics were calculated.
