Hello,

There is a proposal floating around to use the UGRID conventions for
unstructured grids in CMIP6 data. One issue is that the CF Convention
specifies a specific string for the "Conventions" and the UGRID
convention specific a different specific string. Is there any chance
of modifying CF to accept, e.g. Conventions = "CF-1.8, UGRID-0.9"?

This is already possible, as per the netCDF users' guide:

https://www.unidata.ucar.edu/software/netcdf/docs/netcdf.html#Attribute-Conventions

It is possible for a netCDF file to adhere to more than one set of
conventions, even when there is no inheritance relationship among the
conventions. In this case, the value of the `Conventions' attribute may
be a single text string containing a list of the convention names
separated by blank space (recommended) or commas (if a convention name
contains blanks).

Best,

Maarten Sneep
