[MITgcm-support] OBCS Error with 36km Arctic config

[Manfredi Manizza]

Hi Zang and Alessandro,

a possible strategy I adopted in the past with the 18-km Arctic set-up 
is to read the file with MATLAB or an any other similar software, then 
generate the files for the same period again repeated at least twice so 
that you can extend your simulation for a longer period.  You can also 
average values for the same period 1991-2002 in a climatological years 
and then repeat that climatological file of physical properties for N times
when N is the numbers of years you want to simulate. N*12 should be the 
time dimension if you use monthly values.

As far as I know the effect of boundary conditions should not be that 
crucial to affect the physical solutions
inside the Arctic domain.

Cheers
Manfredi
