Support for external atmosphere model libraries
It would be very nice to be able to more or less directly import atmosphere models, such as the brand new version of NRLMSIS:
- https://agupubs.onlinelibrary.wiley.com/doi/pdf/10.1029/2020EA001321
- https://github.com/space-physics/nrlmsis2.0
I know there might be some licensing problems, since e.g. MSIS-2.0 license is very restrictive.
An another way could also be allowing something a bit more flexible than 5-layer model as in CORSIKA7, which in practice forces the user doing the fit to make some tradeoff between the closeness to the model and the maximum height that will be properly described (at least that's my experience).
