Re: [CF-metadata] Proposal for standard names: tropospheric trace gas column amounts

2012-12-21 Thread Cameron-smith, Philip
Hi Andreas, et al, All the std_names seem to follow existing patterns. As mentioned in my previous email, I think the units should be mol/m2 for consistency. Best wishes, Philip --- Dr Philip Cameron-Smith, p...@llnl.

Hi All, All of the std_names that count atoms and molecules currently have canonical units that use moles and meters, so I would want to continue that. I had not realized that udunits did not include molecules. To the udunits experts: How hard is it to add 'molecules' permanently, using the

2012-12-21 Thread Jonathan Gregory
Dear Andreas and Martin I agree with Martin that if layers can be defined numerically these numerical limits should not appear in the standard_name. The usual way to do it would be with a coordinate variable (either with a dimension of size 1, or a scalar coordinate variable) whose bounds specify
