Dear Markus Thanks for your email. Your proposed solution of "dried aerosol" looks sensible to me. I like the distinction from "dry" and "ambient" and its meaning is obvious to me as well. Best wishes Jonathan ___ CF-metadata mailing list CF-metadata@c

Dear Philip, John, and all, after discussing this issue also offline with a few peers, and including the comments of Philip and John, I think I can propose a solution: The original problem: CF aerosol variable names so far use the terms "_due_to_ambient_aerosol" and "due_to_dry_aerosol". For va

I think the fundamental question is: Is the data in every measurement sense fully interoperable with data that is _due_to_ambient_aerosol? If not, why not? In this case, it isn't fully interoperable because the values have been changed due to a process (partial drying) that's been applied, ri

Dear all, a couple of weeks ago, I proposed a list of new CF variable names for surface aerosol optics properties (last version repeated at the end of this mail). We had a good discussion of the proposal, and due to lots of valuable comments, we managed to even out almost all issues, except for

Hi Philip, hi Jonathan, thanks for your constructive input! It seems we are circling in on most of the debated points. Even though it may seem cumbersome, I think it will be of great value to have variable names which are common between the modelling and observational communities. Please see my

Hi Philip, thanks for doing such a thorough job reviewing my proposal! Indeed, I should have seen a few of the points you mention even before I posted my proposed standard names. I therefore included, below my comments, an updated version of my proposed list of standard names and pertaining def

2012-03-07 Thread Markus Fiebig
Dear all, since the WMO Global Atmosphere Watch (GAW) programme is moving towards using CF standard names as standard vocabulary, I'd like to propose a few standard names that represent aerosol properties being observed at the GAW surface sites. Since there seem to be various opinions about the
