OK, fair enough. Having made this error I feel obligated to look a bit deeper, but I am having trouble finding hard numbers so far.
Interestingly, the closest I have come is in another PowerPoint by David Streets: http://www.giss.nasa.gov/meetings/pollution2002/present/1_streets.ppt Relevant are slides 5 and 8. Slide 8 supports the impression that the trend in aerosol emissions from Chinese power plants is sharply downward, and that this applies to sulfur as well. Slide 21 is also interesting in view of the discussion about possibly insufficient in situ measurement of important processes. mt On 3/19/07, Raymond Arritt <[EMAIL PROTECTED]> wrote: > > > [EMAIL PROTECTED] wrote: > >> See p 3 of this powerpoint: > >> > >> http://www-new.mcs.anl.gov/climate/cwg/slides/ANL_CCW_Streets.ppt > >> > >> Aerosols are dominated by low-tech burning of fuels for heat, and by > cheap, > >> primitive factories and motors. > > > > Isn't that just for black carbon rather than sulphur, and isn't black > > carbon a positive forcing agent, and sulphur related aerosols are > > responsible for cooling? > > The presentation is devoted specifically to carbonaceous aerosols, not > sulfates (sulphates) or aerosols in general. > > Ray > > > > > --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups Global Change ("globalchange") newsgroup.
