Novakov, T

The principal goal of the research described is to assess quantitatively the relative amounts of primary and secondary carbonaceous material in atmospheric aerosols and to differentiate between secondary carbonaceous species produced by photochemical and nonphotochemical reactions. The approach used most extensively involves the use of an optical attenuation technique, combined with total particulate carbon determination. The black component of soot, which is an unambiguous tracer for primary emissions, can be conveniently monitored because of its large and uniform optical absorptivity. The black carbon content of the particles can easily be determined by an optical attenuation method. Determination of total particulate carbon mass enables the study of the relations between the black and the total carbon content.
