ERA40 Model Resolution Gridded Surface and Single Level Forecast Fields from ECMWF

This dataset contains 75 variables from the from the forecast cycle of the ERA-40 model. 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 The analysis fields have been archived in ds117.0 [rda.ucar.edu/datasets/ds117.0/].

All data are archived on an N80 [rda.ucar.edu/datasets/common/ecmwf/docs/n80Rpnts.html] reduced gaussian grid four times per day. 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.
