Aerosol species, light-absorbing

Graphitic carbon particles are thought to be the most abundant light-absorbing aerosol species in the atmosphere (2,). Comparison of elemental carbon concentrations from the present study to measurements of b. is presented in Figure 5. A regression line drawn through those data has the equation ... 

Photochemically-active species have been identified in aerosol particles, but the processes following light-absorption are poorly understood. Once a photon is absorbed into a typical marine aerosol droplet, how does it partition What are the most important likely paths and products Table 3 summarizes the possible photochemical processes that may occur on fight absorption within a marine aerosol particle. Admittedly this is a very approximate estimate based on some typical light-absorbing constituents, their concentrations, relative ab-sorptivities (see Table 2), and known quantum yields and products.
