Future experiment (2106-2116) representing a climate warmer by 1.5°C than under pre-industrial conditions (1861-1880) following the AMIP design described by Taylor et al. (2012) .
Anthropogenic external forcing data are taken from CMIP5 RCP2.6 of the last decade of the 21st century. Natural external forcing conditions are the same as those in the current decade experiment of this CERA experiment except for sea surface temperature (SST) and sea ice coverage (SIC). SST is calculated by increasing the SST used in the current decade experiment by the difference between the climatological monthly mean results of the CMIP5 Multi Model Means during 2091-2100 in RCP2.6 and during 2006-2015 in RCP8.5. The SST correspond to a warming of the global near surface temperature by 1.55°C as compared to pre-industrial conditions. SIC is calculated from the SST using correlations between observed SST and observed SIC from 1996-2015.
The experiment includes 125 realizations contributed by the NCC with NorESM1-HAPPI.
