Deviations from the O 3 –NO–NO 2 photostationary state in tropospheric chemistry

Abstract

A theoretical study of the magnitude and origin of deviations in the photostationary state relation, [Formula: see text] has been carried out by computer simulation. Various homogeneous tropospheric mixtures were chosen with initial pollutant concentrations varied from those of highly polluted to very clean atmospheres. Even for the homogeneous conditions assumed here, strong negative deviations were observed ([O 3 ] t [NO] t /[NO 2 ] t
