@jr3cermak IMHO setting `reuse_weights=True` to compute and save weights is confusing. The current behavior allows to save weights when `reuse_weights=False` and `filename="something.nc"` and then one can re-load the weights using...

agreed, I think something in the logic has been broken. @huard and @aulemahal any thoughts on this? One workaround is for you to specify explicitly the name of the weights...

Hi @christophrenkl this is a feature that, as an oceanographer, would like very much to have as well. AKAIK the ESMF library does not have the 3D interpolation available so...

@benjamin-cash you might be able to detect the discontinuity using first or second order derivatives and tests for monotonicity

we should use #228 to generate a synthetic tripolar grid for the testing. I have a PR that fixes a minor testing issue that needs to go through first then...

Salut @huard The code basically works, I've been working on a test with synthetic data from tripolar to regular lat/lon but I can't get it to generate different solutions with...

I think @rabernat is the owner of the xgcm RTD

@sanAkel this could be a good starting point: https://github.com/NOAA-GFDL/FMScoupler/blob/9da2d61f74671ccee775553a36439260c9241383/shared/surface_flux.F90#L841 feel free to ping me on this as I'm also interested.

LGTM +1 Very useful addition!
