Have you run into one of our calculations that doesn't work for your staggered dataset?

I think going down the "vector derivative-based `divergence` of the scalar gradient" is the right choice here since it's the truest to the physics and involves the least amount of...

I think it makes sense to include this in MetPy. Not sure when we'll have cycles internally to implement this, but would be happy to review a PR contributing this...

I doubt a decision will be made before 0.6, but it's good to have this hanging around so we can move quickly when we have the cycles for it.

Should also link to the [AMS 2021 talk](https://www.youtube.com/watch?v=X_aQzZ7jNRs&feature=youtu.be) somewhere.

Here's a minimal reproducer: ```python from datetime import datetime from metpy.cbook import get_test_data from metpy.io import parse_metar_file from metpy.plots.declarative import PlotObs, MapPanel, PanelContainer sfc_obs = parse_metar_file(get_test_data('2020010600_sao.wmo', False)) obs = PlotObs()...

@sgdecker Can you open that as a new feature request? It's reasonable to do for the declarative interface.

That equation can also be made dimensionally sound by giving all of the constants their correct dimensionality. Given that the equation works for degC, that means there is some implied...

I haven't started using annotations in MetPy (yet), so I don't have any practical experience to rely on to see any obvious gotchas. In general, though, those look reasonable.

@hgrecco NumPy has also been adding annotation support for `ndarray` inputs, so it would be important IMO to make sure whatever is done here compatible/sensible with that.
