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 this dataset 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.
CERA-20C is the ECMWF 10-member ensemble of coupled climate reanalyses of the 20th century, from 1901-2010. It is based on the CERA assimilation system, which assimilates only surface pressure and marine wind observations as well as ocean temperature and salinity profiles. It is available on 37 pressure levels.
It is an outcome of the ERA-CLIM2 project.
