    <dct:description>The Twentieth Century Reanalysis Project is an effort led by PSD and the University of Colorado CIRES Climate Diagnostics Center to produce a reanalysis dataset for the entire twentieth century, using only surface observations of synoptic pressure, monthly sea surface temperature and sea ice distribution. The observations have been collected with the support of the Atmospheric Circulation Reconstructions over the Earth initiative, and working groups of GCOS and WCRP. The Project uses a recently-developed Ensemble Filter data assimilation method which directly yields each six-hourly analysis as the most likely state of the global atmosphere, and also estimates uncertainty in that analysis.  This dataset will provide the first estimates of global tropospheric and stratospheric variability spanning 1871 to present at six-hourly resolution (V2). In Version 2, data files are also produced for daily and monthly values of the variables. The first version has global coverage spanning 1908-1958, and two degree longitude-latitude horizontal resolution (V1).
