Hi Steve, I wouldn't disagree with that argument. If this part of the convention hasn't found even modest support/adoption in software by now, then it's probably not going to happen - especially in view of the latest netCDF-4 functionality (although that's not an option for CMIP5, where the decision was made to go with vanilla netCDF-3 classic, IIRC). In which case I'd agree that deprecating compression by gathering at the next version of CF is probably worth consideration. Cheers, Phil

You should anticipate serious interoperability barriers if you choose to use it. In view of the option to use "chunked" netCDF4 compression transparently with the netCDF3 classic API, there's a strong case that the old Compression by Gathering should be formally deprecated. - Steve
