Dear all,
In reply to Markus email dated of 01/25/2014 (below)
Thecurrent CF definitions for "aerosol" are:
/-"Aerosol" means the suspended liquid or solid particles in air (except
cloud droplets).
- "Ambient aerosol" is aerosol that has taken up ambient water through
hygroscopic growth. The extent of hygroscopic growth depends on the
relative humidity and the composition of the aerosol.//
//- "Dry aerosol" means aerosol without water.
//
/
We could eventually propose to modify as follows:
* "ambient aerosol" to "aerosol" ; New definition: "Aerosol" means
the suspended liquid or solid particles in air (except cloud
droplets). The aerosol takes up ambient water through hygroscopic
growth. The extent of hygroscopic growth depends on the relative
humidity and the composition of the aerosol.Unless a specific
relative humidity is indicated, it refers to the aerosol in the
ambient air conditions.
* "dry aerosol" : no change
* "black_carbon" to "elemental_carbon". Definition: A form of carbon
that is essentially pure carbon rather than being chemically
combined with hydrogen and/or oxygen. It can exist either in an
amorphous or crystalline structure (Shah and Rau, 1990)
but then it would require to indicate that earlier standard names
"black_carbon" and "ambient_aerosol" are unrecommended synonymes ?
