ERA40 Monthly Mean Model Resolution Gridded Surface and Single Level Forecast Fields from ECMWF
Listed in NASA Earthdata CMR
Description
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. Descriptions of the series organization and direct links to information about all ERA40 products are available [rda.ucar.educgi-bin/joey/era40sum.pl?ds=ds118.0].
This dataset contains monthly means for 73 surface and single level variables from the forecast cycle of the ERA40 model. Means are available for the 3 and 6 hour forecasts for each synoptic hour (00, 06, 12 and 18 UTC) as well as a diurnal mean for the 6 hour forecast. All data has been archived on the reduced N80 Gaussian grid.

Monthly means have been computed for each analysis hour as well as a diurnal mean. 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/].
