This is something I feel I could work on! Would you feel comfortable adding metpy as a dependency, or would that be a bit heavier than you were thinking? Incorporating metpy would also give us access to easy unit handling and conversions, if we wanted to implement that in the future.

Metpy is great, and it is always a bonus for us to use unidata tools (UCAR connection).
Metpy seems really well supported and widely used, so happy to have it as a dependency if you think it is the right tool for the job!

Thinking about this a bit more, Metpy could be great to leverage for their observational data. I think prepbufr is in their roadmap, so you could use this to convert observations (e.g. prepburf, etc.) to obs_seq directly in python.
