Dear Philip, Thank you for your reply. In the meantime, I indeed found the variable you propose. Dobson Unit would be much more convenient instead of m, as it is much more used in the scientific community. Best regards Christophe On 19/09/2012 01:06, Cameron-smith, Philip wrote: Hi

Hello Ben I have put an example section at the bottom of the wiki page https://cf-pcmdi.llnl.gov/trac/wiki/PotentialDataModelTypes#Example1 I think you are right that including examples helps to illustrate the conversation, I hope I have done so here. In particular, I have noted:

Dear David, Thanks for the update. The Dobson Unit is also commonly defined as (from Wikipedia): One Dobson unit refers to a layer of gas that would be 10 µm thick under standard temperature and pressure http://en.wikipedia.org/wiki/Standard_temperature_and_pressure^[1]

Hi Jonathan: The range for the data variable is not error/uncertainty. Rather, the data variable is one of a set of data variables needed to define the current environmental conditions at a location. The specific data variable is an energy band with an upper and lower limit where the energy

Dear Randy a possibility would be new modifiers to indicate the lower and upper bounds. (I think you are suggesting using the existing ancillary variable convention construct). I don't think they'd be ancillary variables, because there isn't a main variable to hang them from, as you say

Hi All, The problem as I see it, is that the two versions of Dobson Unit are effectively equivalent via the ideal gas law. Hence, I see Dobson unit get defined both ways, and since DU is used as the unit the difference is hidden and irrelevant, except for CF because we insist on connecting it
