Add regional runoff regridding script and use its output #4

Closed angus-g closed 2 years ago

Adcroft's regrid_runoff only works on global destination grids, so it's not suitable for for our regional domain. Using a similar technique, we can regrid the runoff onto the regional grid, conserving the total runoff. This seems to avoid the issues at the corners, and along the eastern boundary.

Hopefully a reasonable resolution to the issue raised here: https://github.com/COSIMA/mom6-eac/issues/1#issuecomment-1080152466?

@russfiedler -- thought maybe you can have a look at this, then if we are happy I will test the new runoff once Gadi comes back online.

Sorry, I only read moderately basic Python. I can figure out what's trying to be done but I have no idea if it's bombproof.

Why not use @russfiedler 's runoff regridding code that we used for ACCESS-OM2?

@aidanheerdegen That would work. My (our) code only searches for source points within 50Km by default.
