Search ECMWF datasets

Due to the move of our Meteorological Archival and Retrieval System (MARS) to the new Data Centre in Bologna there will be no or degraded access to the archive datasets listed below at times between June and October 2022.
Please visit our dedicated data centre migration pages for more information.
Thank you for your patience and support during this important move, which will allow exciting scientific developments and overall better service.
