Re: [CF-metadata] new standard name proposal for total ozone in DU
Hi Alison and Roy, I think that the solution you proposed is suitable to the O3 community. Having the canonical unit (mol/m-2) for the O3 columns in the vocabulary server is fine as long as it is not a problem to use a different unit (Dobson Unit) in the NetCDF files. The important point is that the variables are expressed in the commonly used units so that the users can understand the file content at a glance. Best regards, Christophe On 5/12/2012 11:30, alison.pamm...@stfc.ac.uk wrote: Dear Roy and Christophe, As Roy says, we usually use SI units for the canonical unit in the standard name table. There are a few exceptions, for example, age_of_sea_ice has units of year and age_of_surface_snow has units of day, whereas the SI unit for both quantities would be the second. Also, we allowed some of the recently added salinity names to have canonical units of g kg-1 which I'm not sure adheres strictly to SI. I think the reason for having the exceptions was simply that they are the units that are always used with the named quantities. For Christophe's ozone name, atmosphere_mole_content_of_ozone, the proposed definition is ' "Content" indicates a quantity per unit area. The "atmosphere content" of a quantity refers to the vertical integral from the surface to the top of the atmosphere. For the content between specified levels in the atmosphere, standard names including content_of_atmosphere_layer are used. The construction "atmosphere_mole_content_of_X" means the vertically integrated number of moles of X above a unit area. The chemical formula for ozone is O3.' Whatever we decide about the units, I think we should add the sentence 'atmosphere_mole_content_of_ozone is usually measured in Dobson Units which are equivalent to 446.2 micromoles m-2'. Roy's proposed solution of having canonical units of mol m-2 while using Dobson Units in the data files is certainly consistent with the CF conventions. As long as UDUNITS knows how to convert the units in the file to the canonical units there is no problem. Christophe, would that be acceptable to the ozone community? Roy, is there any technical reason why we couldn't map to Dobson Units in the vocabulary server if that were the preferred solution?

[CF-metadata] new standard name proposal for total ozone in DU
Dear CF colleagues, I've already exchanged some e-mails with some of you about the appropriate standard variable to use for total ozone columns in Dobson Units. It turns out that there is currently no suitable standard name for this. So I'd like to propose the following variable name for total ozone columns based on recommendations I was given: - "atmosphere_mole_content_of_ozone" expressed in Dobson Units. Dobson Unit (DU) is already defined in the UDUNIT package ans is equivalent to 446.2 micromoles m-2. - The definition would be something like : "Content" indicates a quantity per unit area. The "atmosphere content" of a quantity refers to the vertical integral from the surface to the top of the atmosphere. For the content between specified levels in the atmosphere, standard names including content_of_atmosphere_layer are used. The construction "atmosphere_mole_content_of_X" means the vertically integrated number of moles of X above a unit area. The chemical formula for ozone is O3. Thank you for considering this new variable name.

Re: [CF-metadata] request for new standard name
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] <http://en.wikipedia.org/wiki/Dobson_unit#cite_note-0> , sometimes referred to as a 'milli-atmo-centimeter.' For example, 300 DU of ozone brought down to the surface of the Earth at 0 °C <http://en.wikipedia.org/wiki/Degree_Celsius> would occupy a layer only 3 mm thick" That would match better the variable name.
