NCEP/NCAR Reanalysis

The NCEP/NCAR Reanalysis reanalysis data set (1948-2014) was a continually updating gridded data set that represented the state of the Earth's atmosphere, incorporating observations and numerical weather prediction (NWP) model output from 1948 to September 2014. It was a joint product from the National Centers for Environmental Prediction (NCEP) and the National Center for Atmospheric Research (NCAR).

Accessing the data[edit]

The data is available for free download from the NOAA Earth System Research Laboratory[1] and NCEP.[2] It is distributed in Netcdf and GRIB files, for which a number of tools and libraries exist.

Uses[edit]

  • Initializing a smaller scale atmospheric model
  • Climate assessment

Subsequent updates[edit]

Since then NCEP-DOE Reanalysis 2[3] and the NCEP CFS Reanalysis[4] are 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.[5]
