The coverage API is an abstraction over the raw NetCDF layer. I do not know if these internal implementation details are accessible. Perhaps Daniele can confirm? > 2.)

What's the way to get the proper values? I do not think you should have to use a NetCDFProjection. What version of GeoTools are you using? There were some recent changes in the NetCDF-Java library affecting longitude handling but I think only in GRIB2 files. Excessive or inconsistent tampering with longitudes might be a bug in GeoTools.
