[MITgcm-support] Time-Dependent Periodic Forcings

Hi Suhani

You may want to carefully read: https://mitgcm.readthedocs.io/en/latest/getting_started/getting_started.html#mitgcm-input-data-file-format as well.

Cheers,   Jody

You don't often get email from dmenemenlis at gmail.com. Learn why this is important<https://aka.ms/LearnAboutSenderIdentification>
The core MITgcm routines  (MITgcm/model) do provide some basic capability for prescribing forcing, see for example:
https://github.com/MITgcm/MITgcm/blob/master/verification/tutorial_global_oce_latlon/input/data

But pkg/exf has many more capabilities and flexibility: https://mitgcm.readthedocs.io/en/latest/phys_pkgs/exf.html

Thank you! Based on these examples, it seems like you need to use the exf package to prescribe the forcing. Is that correct?
