Atmospheric Radiative-Photochemical Process for the calculation of Vertical Ozone Concentration

Abstract

The variations of vertical ozone concentration were calculated by one dimensional radiative-photochemical model with the different chemical species and reactions, and radiative parameterization. The numbers of photochemical reaction and chemical species for these calculations are 109 and 40, respectively. And the ultraviolet spectral region of solar radiation were parameterized with the three groupings of 68, 34, and 17 spectral bands. As a result, the ozone concentration decreased with increasing chemical reaction number, because of the increasing ozone destruction effect in their reactions. The photolysis rate variations of O2 and O3 with different radiative parameterizations of ultraviolet spectral region were maximum 30～40% in the stratosphere and troposphere, also the ozone concentration varied maximum 0.5% in the stratosphere and more than -4～4% in the mesosphere.
