Hi John,
1) I don't think the CF conformance checker is that sophisticated, but Ros please put me right if that's wrong. 2) That thought had occurred to us as has the possibility that it needs to be per meter cubed and not per cubic meter. We'd have done some experiments, but editing text in NetCDF files isn't that simple so we thought we'd ask first and save some work. 3) My understanding is that the actual units including prefix are included as the parameter variable in CF NetCDF and not the canonical units. Again, please correct me if this is wrong. Cheers, Roy. Please note that I now work part-time from Tuesday to Thursday. E-mail response on other days is possible but not guaranteed!

If anyone has found a deep description of UDUNITS I'd love to know of it. So far it seems like one has to study and do tests with the code to understand all the details.

Anybody know why it's wrong? Cheers, Roy. ________________________________ This message (and any attachments) is for the recipient only.
