ERA40 Model Resolution Gridded Upper Air Forecast Fields on Model Levels from ECMWF

All Variables are from the forecast cycle of the ERA-40 model and are archived at T159 spectral resolution in spherical harmonics or the reduced N80 gaussian grid with a resolution of approximately 125 kilometers. 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.

The analysis fields have been archived in ds117.2 [rda.ucar.edu/datasets/ds117.2/]. The ECMWF Re-Analysis (ERA40) is a global atmospheric analysis of many conventional observations and satellite data streams for the period Sept,1957- Aug,2002. There are numerous data products that are separated into dataset series' based on resolution, vertical coordinate reference, and likely research applications.
