ERA-Interim is the latest ECMWF global atmospheric reanalysis of the period 1989 to present.
ERA-Interim products can be retrieved from MARS (class=ei, expver=1) or downloaded from the
ECMWF Data Server. Please see the ERA-Interim archive document
for a full description of the available products. When using the data server, please refer to our list of
frequently asked questions.
ERA-Interim products on MARS and the data server are normally updated once per month, allowing a two-month delay for
quality assurance and for correcting technical problems with the production, if any. Product updates will be announced here as soon as
they occur.
