ERA40 2.5 Degree Latitude-Longitude Gridded Upper Air Analysis on Pressure Surfaces 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 September 1957 to August 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=ds118.1].
This dataset contains 11 variables on 23 pressure surfaces on an equally spaced global 2.5 degree latitude-longitude grid. All variables are reported four times per day for the entire period. 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 [rda.ucar.edu/datasets/ds627.0/].
