Greetings! Apologies for the delayed response. I would recommend looking at the updated version of this notebook that is hosted on Project Pythia: https://github.com/ProjectPythia/metpy-cookbook/blob/main/notebooks/synoptic/Upperair_Obs.ipynb https://projectpythia.org/metpy-cookbook/notebooks/synoptic/Upperair_Obs.html We have updated this to use functionality that exists within MetPy to directly at the lat/lon information to a dataframe based on a column of station IDs. This used station information baked into MetPy. The relevant lines are: from metpy.io import add_station_lat_lon df = add_station_lat_lon(df) Hope this helps!
