That would be extremely helpful @jbusecke! Also super interested in density coordinate interpolation, and we (and other projects) might think of a couple other needs as projects progress, so perhaps a centralized technical project would be more efficient? This is already great text for a proposal:

> I would propose the implementation of common vector calculus operators like grad, div, curl into the [xgcm](https://xgcm.readthedocs.io/en/latest/) module. Recent addition of [automatic grid metric handling](https://github.com/xgcm/xgcm/pull/99) builds the foundation for these operators and this workshop presents a fantastic opportunity to develop these new function on top while simultaneously testing them with a variety of model outputs.
