JGregory: Content Explanation

We have used "content" in a lot of standard names to mean the amount of something per unit area i.e. a vertical integral. Do you think e.g. "atmosphere ozone content" in kg m-2 isn't clear enough terminology? --JonathanGregory 16:51, 22 May 2006 (EDT)

......RHusar: Content Explanation

'Vertical burden' is also used to describe measured column concentrations. It may take a bit of getting used to, but I have no objections to ozone_content. --Rhusar 19:19, 22 May 2006 (EDT)

......CTextor: Content Explanation

I think in the chemistry/aerosol community "content" would rather be understood as a total mass, the amount of something per unit area would rather be called 'load' or 'column'. Therefore I would now suggest to use vertical_burden which seems less ambiguous to me. --Christiane Textor (Christiane) 12:11, 2 June 2006 (EDT)

JGregory:in_air vs. atmosphere

The difference between atmosphere and in_air is that atmosphere is used to refer to large-scale properties, and in_air to locally measured ones. Hence the distinction between e.g. mass concentration in air, and atmosphere content. Chemical concentrations would be in_air (as you have done), and hence distinguished from in_sea_water etc. If a given quantity could appear in places other than air, it is correct to be explicit. --JonathanGregory 16:51, 22 May 2006 (EDT)

JGregory: mole or mass fractions

You may indeed prefer mole_fraction for some quantities and mass_fraction for others. That would be your own decision for your project, but of course another project might make a different choice. --JonathanGregory 16:51, 22 May 2006 (EDT)

......CTextor: mole or mass fractions

The use of either mole_ or mass_ fraction varies within the community, so I followed the suggestions of the PRISM project. But then aerosols should allways be in mass and gases in mole fraction for consistency. --Christiane Textor (Christiane) 12:11, 2 June 2006 (EDT)
