Hi Miriam,
sorry for no answers in the past.
I think that all the other devs were busy or, as you said, have no good
feedbacks for you.
I personally didn't see your latest email (somehow buried within all the
other mailing lists), sorry about that.

Most part of the NetCDF code is at GeoTools level in the coverage-multidim
containing some common API for multidimensional classes and a module
specific to netcdf:
https://github.com/geotools/geotools/tree/master/modules/plugin/coverage-multidim


The GeoServer multidimensional training material that you have already
checked contains some additional information.
Most part of custom dimensions is handled at ImageMosaic level with
additional mapping based on properties extractors where the NetCDF lowlevel
part mainly deal with the TZXY dimensions and related coordinate axis.
As far as I remember, the low level binary index in NetCDF has specific
mappings for time and elevation related dimensions.
This is the class reporting that warning message related to unsupported
axis type:
https://github.com/geotools/geotools/blob/master/modules/plugin/coverage-multidim/netcdf/src/main/java/org/geotools/imageio/netcdf/NetCDFGeoreferenceManager.java#L380

https://github.com/geotools/geotools/blob/master/modules/plugin/coverage-multidim/netcdf/src/main/java/org/geotools/imageio/netcdf/NetCDFGeoreferenceManager.java#L574

Best Regards,
Daniele
