    7 Obviously, observations are not yet available for 2100 so we will use simulations. We will use AR5 simulations from the Earth System model of the IPSL called IPSL-CM. Archives of these simulations can be found at the IPSL https://forge.ipsl.jussieu.fr/igcmg/wiki/IPSLCMIP5/Centennal/IPSLCM5A-LR. Simulations with a higher version number typically denote simulations for which previous problems were fixed. We used

Simulations with a higher version number typically denote simulations for which previous problems were fixed. We used v3.rcp45.4, for which the simulations between 2006 and 2100 can be found at ccc/store/cont003/dsm/p86denv/dmf_import/IGCM_OUT/IPSLCM5A/PROD/rcp45/v3.rcp45.4/ATM/Analyse/TS_MO. These are post-processed time series for the period 2006 to 2100. There is one time series per variable and the time series has a monthly time step. The time series required to set the boundary conditions are those for sea surface temperature and the sea ice extent:

Hence the need of SST and sea ice files for all years in the experiment. These newly defined years now have to be used in COMP/lmdz.card. Therefore, change the boundary files as follows:
