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 datasets listed here 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.

MARS request efficiency
Data at this level are stored in one file on tape and are best retrieved with a single MARS request and not iterated through. For more information, please refer to our guidelines to write efficient MARS requests.
