[python #NMJ-899116]: Metpy/Cartopy Issues

Thank you for providing the data! That was very helpful. However, I was able to 
plug it into the code you provided. The only way I was able to recreate your 
problem is if I didn't import anything from MetPy. Then the code returned the 
same error you provided. As long as you import something from MetPy, the xarray 
accessor should work.
