On second reading this is more of a chemistry rather than a physics
question (radiative transfer).  I suggest sending mail to NCAR (greg woods
or peter gross) and have them forward it to their people.
Briefly: haze can include water, but the water can have such things
as sulfuric and nitric acids, other heavier than air, non-colorless gases
(air being around 30 g/cm^2), particulate matter (lead for instance) which
serve as condensation nuclei.
