While I don't think that our [current accessor documentation](https://unidata.github.io/MetPy/dev/api/generated/metpy.xarray.html#module-metpy.xarray) is that bad at this point, it may be worth considering using the upcoming [`sphinx-autosummary-accessors`](https://github.com/xarray-contrib/sphinx-autosummary-accessors) extension to standardize around how other...

Problem: Trying to reproduce the output from GEMPAK for the `laplacian` calculation. MetPy has a different implementation of calculating the Laplacian by using the sum of the second derivative of...

GEMPAK Conversion

Right now, adding a new data file requires adding the hash `static_data_manifest.txt`. There is no need for a human to do this task. We can rely on GitHub's own hashing...

It would be useful if one could calculate the thickness of layers of the full atmosphere in one go, i.e., if `thickness_hydrostatic_from_relative_humidity()` and `thickness_hydrostatic()` would (optionally) not only return the...

#### Description Of Changes Had fun playing whack-a-mole to enable nitpicky for sphinx. This is going to be a good thing to have to clean up our docs, as it...

Some MetPy functions, such as gradient and advection, allow the user to supply arrays of deltas rather than a single value, but vorticity (and its relatives) does not. Vorticity is...

This contains implementations of the different methods of calculating saturation vapor pressure referenced in #508. When a method is chosen, the others can be removed from the thermo file and...

#### Description Of Changes In this pull request, I've modified the equilibrium vapor pressure (e_s) calculation to a more accurate formulation based on Murphy and Koop (2005; reference added). I've...
