Add/enable metadata extractors for atmospheric data?

Whenever we add sensing the repos from ATRIS:

@matrss - it seems that netcdf5 is used for some data files. I wonder if there is some formalization on top of that (e.g. like we have https://www.nwb.org schema on top of hdf5) for files or even more interesting - for some dataset level descriptors (like we have https://bids-specification.readthedocs.io/en/stable/ in neuro). May be there is already some datalad extension with metadata extractors like we have https://github.com/datalad/datalad-neuroimaging/ with https://github.com/datalad/datalad-neuroimaging/blob/master/datalad_neuroimaging/extractors/bids_dataset.py etc ?

The most common data formats I am aware of are probably netCDF (in all of its versions), and grib (1 and 2). For metadata in netCDF files there are at least the CF conventions as a common denominator: https://cfconventions.org/. On a dataset / directory structure level I am not aware of a common standard.

A metadata extractor for netCDF or grib doesn't exist yet to my knowledge, but would probably be nice to have. Though I am not up-to-speed on the current way of metadata handling in DataLad...
