Restart ACCESS-CM1 from different year

After prepare the restart files:

Due to leap year the date needed to update in the restart files (even though the model did run without these changes! but crashed on 29th Feb.):

• iced.xxxx needs the date updated, using a code Aidan provided Rishav with

• mice.nc-xxxx needs the date updated, just using CDO or NCO

• ocean_solo.res-xxxx needs the date updated, just manually
