MARS - Meteorological Archival and Retrieval System

contains the meteorological forecast/analysis/re-analysis ECMWF data in GRIB format, observations in BUFR format and observations feedbacks in ODB format (ECMWF ad-hoc format).

Access to operational forecasts and analysis as well as observations require to have an account at ECMWF but all REANALYSES can be freely downloaded. The list of freely accessible dataset can be found here

What is in MARS? - Data types and format


Retrieve small data sets from the web-MARS (online web-tool)

Browse the content of the MARS archive, create requests, check availability, retrieve small amounts of data.


Retrieve large data sets from MARS with ecmwfapi

Get your data where you need to run your simulation (local computer, abel, etc.).


File systems and data structure at ECMWF - where to store and get data!

Overview of file systems/domains and quotas on the various domains.


Retrieve larger data sets from MARS on ECgate or HPCF

ECgate is the standard UNIX server, HPCF (High Performance Computing Facility) is the supercomputer.


File transfer via ftp


Retrieve ECMWF fields for FLEXPART


Retrieve high-resolution nested ECMWF fields for FLEXPART


Retrieve historical ECMWF fields (ERA40 and ERA-INTERIM) for FLEXPART


Some operational FLEXPART ECMWF fields are missing – how to get them!


How to read GRIB files!
