Dear all, please excuse if I come in late into this discussion, but I would like to make a few comments about the proposed variable name
"volume_extinction_coefficient_in_air_due_to_mie_scattering_of_ambient_aerosol" As it is written above, the name is self-contradicting. The aerosol extinction coefficient is defined to include both, particle scattering and absorption. The part of the aerosol extinction coefficient that is due to particle scattering is commonly referred to as aerosol scattering coefficient. Also, I need to apologise for not having followed the discussion concerning the use of the term "mie", but it appears rather to confuse than to clarify in the context here. Even though the term Mie-particle is colloquially used for a spherical, internally well mixed aerosol particle, such a particle exists only in theory or in some numerical model. If the variable name is also to be used for an observed quantity, which I think it should, the term "Mie" should be avoided. How about putting this much simpler, and name the property: "volume_scattering_coefficient_in_air_due_to_ambient_aerosol" or, to avoid even more confusion: "volume_scattering_coefficient_at_stp_in_air_due_to_ambient_aerosol" Regards, Markus _______________________________________ Dr. Markus Fiebig Dept.

März 2012 15:26 To: cf-metadata@cgd.ucar.edu Subject: [CF-metadata] warming up old stuff - part 1: aerosol mie scattering Dear all, on Oct 4, 2011, I had made a proposal to add "volume_extinction_coefficient_in_air_due_to_mie_scattering_of_ambient_aerosol". This had been discussed and after clarification of a lower-case "mie" I was under the impression that this has been accepted. However, it is not on the list, nor can I find it in the current status of proposals. I request addition to the list within 1 month.
