ERA40 Model Resolution Gridded Upper Air Analysis on a Potential Vorticity Surface 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=ds118.1].
This dataset contains 7 variables on the PV+-2 surface. All of the variables are on the N80 reduced gaussian grid. All variables are output 4x a 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 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/].
