Effects of aerosol scattered radiation on minor atmospheric species concentrations in a one-dimensional model

Abstract

The effects of solar radiation scattered by aerosols on minor atmospheric species concentrations were examined by a one-dimensional transport-kinetics model with radiative transfer model including the effects of absorption and multiple scattering by molecules and aerosols. The absorption and scattering of aerosols significantly affect the photodissociation rates of optically active species and lead to changes in the concentration profiles of atmospheric minor constituents. For example, a few percent decrease in the stratospheric ozone concentration is simulated for the increased aerosols. The sensitivity of the ozone concentrations to changes in the aerosol loads was also examined
