Summary
Abstract: The ECMWF Re-Analysis (ERA40) is a global atmospheric analysis of many conventional observations and satellite data streams for the period September 1957 through August 2002. There are numerous data products that are separated into dataset series based on resolution, vertical coordinate reference, and likely research applications. This dataset has been segmented into 4 archives: * Surface [http://rda.ucar.edu/datasets/ds117.0/docs/parms.ds117.0.sfc.html] - 46 mostly surface and near surface fields, including 10 meter wind, 2 meter air temperature, soil temperature and moisture, cloud cover information * Vertical Integrals [http://rda.ucar.edu/datasets/ds117.0/docs/parms.ds117.0.vint.html] - 35 fields including column water vapor, column ozone, kinetic energy * Other [http://rda.ucar.edu/datasets/ds117.0/docs/parms.ds117.0.accum.html] - 27 fields, including precipitation, fluxes, radiation, stresses * Log of the surface pressure [http://rda.ucar.edu/datasets/ds117.0/docs/parms.ds117.0.lnsp.html] All data are archived on an N80 [https://rda.ucar.edu/datasets/common/ecmwf/docs/n80Rpnts.html] reduced gaussian grid four times per day. The ERA-Interim data from ECMWF is an update to the ERA-40 project. The ERA-Interim data starts in 1989 and has a higher horizontal resolution (T255, N128 nominally 0.703125 degrees) than the ERA-40 data (T159, N80 nominally 1.125 degrees). ERA-Interim is based on a more current model than ERA-40 and uses 4DVAR (as opposed to 3DVAR in ERA-40). ECMWF will continue to run the ERA-Interim model in near real time through at least 2010, and possibly longer. This data is available in ds627.0 [http://rda.ucar.edu/datasets/ds627.0/].
