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 November 2021 and April 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.
