NCEP/NCAR Reanalysis
The NCEP/NCAR Reanalysis is an atmospheric reanalysis produced[when?] by the National Centers for Environmental Prediction (NCEP) in College Park, Maryland and the National Center for Atmospheric Research (NCAR) in Boulder, Colorado. It is a continually updated globally gridded data set that represents the state of the Earth's atmosphere, incorporating observations and numerical weather prediction (NWP) model output from 1948 to present.
Accessing the data
[edit | edit source]The data is available for free download from the NOAA Earth System Research Laboratory[1] and National Centers for Environmental Prediction (NCEP).[2] It is distributed in Netcdf and GRIB files, for which a number of tools and libraries exist. It is available for download through the NCAR CISL Research Data Archive on the NCEP/NCAR Reanalysis main data page.[3]
Uses

Subsequent updates
[edit | edit source]Since the original NCEP/NCAR Reanalysis, a NCEP-DOE Reanalysis 2[5] and the NCEP CFS Reanalysis[6] have been released. The former focuses in fixing existing bugs with the NCEP/NCAR Reanalysis system – most notably surface energy and usage of observed precipitation forcing to the land surface, but otherwise uses a similar numerical model and data assimilation system. The latter is based on the NCEP Climate Forecast System.[7]
