[MITgcm-support] High frequency velocity outputs for a specific period / location

[Jody Klymak]

Hi Sean,

If you are using diagnostics, you can just make a second set of diagnostics that have the `timePhase` variable set to the time you want start the high resolution saves for.  I don't think this will allow you to make a spatial subset, but you can easily do that in post processing.  It also will not stop saving the high temporal resolution.

The other strategy is to of course restart you model and change the saving frequency, and have the restarted model stop after 30 days.  Again this won't let you save a spatial subset; I'm not aware of any methods that will allow that.

Hopefully that is some small help.

Thanks,  Jody

Hi All


I am trying to produce high-resolution velocity outputs for a specific sub-region of a realistic model run over a specific duration.


Specifically, I have a model simulation for a region domain within the North Atlantic that runs for several years with a time step of 150s and a uniform output frequency of 15 days.


But I would like to have a subset of the velocity outputs with a much shorter interval of 0.5 days over a specific period of 30 days for a given region near Cape Hatteras or near New England seamount, without changing the output frequency for all the entire domain.


How can I do this?


Thanks
Sean
