[MITgcm-support] Questions on configuring AIM surface boundary conditions

[ht]

Dear Community,

I am currently trying to set up atmospheric and land-surface simulations using MITgcm, taking MITgcm/verification/aim.5l_cs as a reference but with my own topography and SST distribution.

I have several questions regarding the configuration files, especially data.aim:

-

It seems that parameters like aim_useFMsurfBC and aim_useMMsurfFc control the use of boundary conditions, but I could not find detailed explanations for these flags. Could you clarify their meanings? Also, should the boundary-condition data be provided as monthly values, or is another temporal format expected?

-

If I want to prescribe only SST from data while letting the model internally compute albedo, land-surface temperature, Sea Ice fraction, and other variables, what is the correct way to set this up?

-

I have attached my current data.aimphys file. Could you please check whether it is correctly configured for this purpose or if modifications are needed?

Thank you very much for your time and support.

Best regards,
Fisher
