National Centers for Environmental Prediction/ Department of Energy (NCEP-DOE) Atmospheric Model Intercomparison Project (AMIP-II) Reanalysis - Gaussian Grid

Brief description

The NCEP/DOE AMIP-II Reanalysis (Reanalysis-2) is based on the widely used NCEP/NCAR Reanalysis. The goal of Reanalysis-2 is to improve upon the NCEP/NCAR Reanalysis by fixing the errors and by updating the parameterizations of the physical processes. The NCEP-NCAR Reanalysis project is a collection of global analyses of atmospheric fields in support of atmospheric and climate research. The Reanalysis involves the recovery of land surface,ship, rawinsonde, pibal, aircraft, satellite and other data, quality controlling and assimilating these data with a data assimilation system. This project uses a state-of-the-art analysis/forecast system to perform data assimilation using past atmospheric observations from 1979 to the present. The data is available in its original 4 times daily format and as daily averages. These are the Gaussian Grid data.
