In this set of experiments, I restored the sea-surface temperature (SST) in a selected region to a certain value and compared the results of these sensitivity experiments to a control run. The control run starts from the year 2014 of the CMIP6 EC-Earth3-Veg r1 historical member, uses a 2000-year constant atmospheric forcing and is 200 years long. The sensitivity experiments all start from the year 2130 of the control run (year 117 if we consider the starting year to be 1) and are 50 years long.

I used 3 different domains for the SST restoring experiments:
|
|
|
1) North Atlantic, between 40N and 80N and between 40W and 20E
|
|
|
2) Northern North Atlantic, between 66N and 80N and between 22W and 20E
|
|
|
1) North Atlantic, between 40N and 80N (latitude of Svalbard) and between 40W and 20E (longitude of BSO)
|
|
|
2) Northern North Atlantic, between 66N (latitude of Iceland) and 80N (latitude of Svalbard)) and between 22W (longitude of East Greenland) and 20E (longitude of BSO)
|
|
|
3) Barents Sea Opening (BSO), between 70N and 77N and between 16E and 20E.

I have applied a SST restoring to the mean climatology of the period 2100-2129 (30 years) plus 1°C, 3°C and 5°C, respectively, for the 3 different domains described above, resulting in 9 different sensitivity experiments, which can be compared to the control run. In order not to have too sharp gradients in SST (and other resulting variables), I have applied a 9-point smoothing at the borders of the domains.
