Adding Advection Schemes

[anthony-meza]

Leaving this note here for myself. I think it would be nice to implement some of the MITgcm advection schemes pkg/generic_advdiff.

In particular, I am interested in implementing things like this. Could be useful if working with model output that does not contain the proper diagnostics, and the model is not worth re-running.

Agreed. Maybe we could start by porting this (below) to MeshArrays.jl ?

could be a good topic for ECCO hackweek 2024, next week, maybe?

I think so! To clarify my initial issue (because it was very vague), I was interested in computing advective flux convergences using the MITgcm diagnostics of temperature and velocity. My thought was that it would be nice if a function that looked something like advective_flux convergence(temperature, velocity, advection_scheme = "third_order_upwind bias_advection". But you should take it in whatever direction you like :)
