ECMWF Reanalysis of the 20th Century - model integrations (ERA-20CM)

An ensemble of ten atmospheric model integrations for the years 1899 to 2009/2010.

There are two versions of the ERA-20CM atmospheric model integrations.

Each is comprised of a 10-member ensemble using:

• Radiative forcing from CMIP5

• Sea-surface temperature (SST) and sea ice cover from HadISST2

Overview of the ERA-20CM versions

Note that ERA-20CMv0 is an experimental version and public access to this data will be disabled in the future. Existing users of ERA-20CMv0 should migrate to the final version as soon as possible.
