### What went wrong? Using `.metpy.parse_cf()` generates: `Could not find variable corresponding to the value of grid_mapping: LatLon_Projection` multiple times. ### Operating System Linux ### Version 1.2.0 ### Python Version...

gdxarray() returns unusable objects from "thinned GFS" files

Here's example 1: ```python from datetime import datetime from metpy.io import GempakGrid import metpy print(metpy.__version__) gem_file_name = '/ldmdata/gempak/model/gfs/21092206_thin.gem' gem_file = GempakGrid(gem_file_name) plot_time = datetime(2021, 9, 25, 6) ht = gem_file.gdxarray(parameter='HGHT',...

Generalize vorticity (and related functions) to allow for map projections

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...

Incomplete Data Reading from URL

This is a feature request identifying what I see as a "hole" in the current ecosystem. There appear to be some GitHub issues related to some of the details; this...

Numerous test failures
