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
|ERA-20CMv0||experimental||Jan 1899 - Dec 2009||Cy37r3||CMIP5||HadISST184.108.40.206||2013|
|ERA-20CM||final||Jan 1899 - Dec 2010||Cy38r1||CMIP5||HadISST220.127.116.11|
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.
Note: Due to an error in the calculation of the daily monthly means (edmo) for a number of parameters for ERA-20CMv0, access to this stream has been disabled. Values from the daily monthly means values can be calculated via the synoptic monthly means (edmm) by averaging over the 8 time=0/to/21/by/3 fields for each month
