[python #FFR-890728]: Any code recommendations to convert altimetry pressure to altitude

Hello, and thanks for following up!

MetPy doesn't require NetCDF for any of its functionality. MetPy does require 
xarray, and some *very* old versions of xarray might require NetCDF, and MetPy 
does not support these very old version of xarray. You might want to make sure 
your environment is as updated as you can get it!

We do have some examples in general you can check out,

    Our user's guide: 
https://unidata.github.io/MetPy/latest/userguide/index.html
    The MetPy examples gallery: 
https://unidata.github.io/MetPy/latest/examples/index.html

We don't have any specific examples of this conversion being used, but I might 
be able to put one together for you with some sample data or if you provide me 
with some shareable data.

If updating your environment doesn't fix your import errors, then follow up and 
let me know, and provide the full code and errors you get if possible. Thanks!


All the best,

Drew
