ERA40 Model Resolution Gridded Upper Air Forecast Fields on Pressure Surfaces from ECMWF
Listed in NASA Earthdata CMR
This dataset contains ECMWF ERA40 model forecasts of geopotential, temperature, wind and moisture variables on 23 constant pressure surfaces for the period September, 1957 to August, 2002.
Description
The forecasts extend out to 36 hours beginning from the 00 and 12 UTC analyses and out to 6 hours beginning with the 06 and 18 UTC analyses. All variables, except moisture, are archived at global T159 spectral resolution in spherical harmonics, while the moisture is archived on a reduced N80 gaussian grid with an approximate horizontal resolution of 125 kilometers.
The analysis fields have been archived in ds117.1 [rda.ucar.edu/datasets/ds117.1/]. The ECMWF ERA40 project is a global atmospheric analysis of many conventional observations and satellite data streams for the period September,1957- August,2002. There are numerous data products that are separated into dataset series based on resolution, vertical coordinate reference, and possible research applications.

Descriptions of the series organization and direct links to information about all ERA40 products are available [rda.ucar.educgi-bin/joey/era40sum.pl?ds=ds121.1] 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 4-D VAR (as apposed to 3-D VAR in ERA-40).
ECMWF will continue to run the ERA-Interim model in near real time thru at least 2010, and possibly longer. This data is available in ds627.0 [rda.ucar.edu/datasets/ds627.0/].
