Hello! Thanks for the follow-up

You're right! I had misunderstood. MetPy does have some functions that may be 
helpful for you here. First, you can calculate height from a given pressure,

  
https://unidata.github.io/MetPy/latest/api/generated/metpy.calc.pressure_to_height_std.html#metpy.calc.pressure_to_height_std

assuming the 1976 US Standard atmosphere 
[https://ntrs.nasa.gov/citations/19770009539].

You also may be able to use MetPy's thickness calculation,

  
https://unidata.github.io/MetPy/latest/api/generated/metpy.calc.thickness_hydrostatic.html

given an entire profile of pressure and temperature, and assumes a hydrostatic 
atmosphere. You can check the referenced equations if needed.

It will be up to you to evaluate if these assumptions are valid for your 
use-case, but we do have these tools available! I hope this helps, and don't 
hesitate to follow up if you need.


All the best,

Drew
