OK, we should improve that.

Yes, I'll correct that.

yes, it should be tendency_of_atmosphere_nitrous_oxide_mole_burden

There is an issue here, also in the definition of `tropopause'. Our intention 
is to have a human readable definition included in the global attributes of 
the file. It would be good to have a broader agreement on how to do this, but 
that may take longer than the CCMVal project.

This problem is would also have to be addressed with existing `_content' 
standard names, so I imagine any resolution found there would apply to 
`_burden' and partial contents and burdens.
