There are some additional steps required to get the CF standards aligned with the new functionality in CMOR3.9 to use new netcdf 4.9.x lossy compression - this will require the addition of a couple of variable attributes if such compression is used - see cf-convention/cf-conventions#403.

It would be great to get this technical work finalized for the CMOR 3.10 release, along with the branded variable changes - all changes occurring to the netcdf variable.
