b.e30_alpha08b.B1850C_LTso.ne30_t232_wgx3.322 #306
Description
Purpose:
Repeat case 321 but start from a spun-up ocean instead of a G-case initial condition.
Case 321 shows a strong cooling at the beginning of the run and a negative RESTOM. We want to confirm whether this behavior is caused by starting from a G case.
Description:
Same as 321 (#305) except:
- start from 287 at year 125
