An asymptotic model for the ozone production in the lower atmosphere

Abstract

The transient ozone generation process in the lower atmosphere is studied in this work, using a simplified set of chemical reactions for the NOx and hydrocarbon photolysis. We obtained a reduced kinetic mechanism and solved the resulting governing equations using the boundary layer theory due to the appearance of two time scales in the problem. We obtained in closed form, the temporal evolution of the ozone concentration as a function of the physico-chemical parameters.
