ABSTRACT We report theoretical photolysis rates for the nitrogen dioxide and ozone in the atmosphere of Mexico City. To estimate the spectral irradiance needed in the calculations, the equation of transfer is solved by the delta-Eddington method. An atmosphere of air, nitrogen dioxide, ozone and dry aerosol is modeled. INTRODUCTION A state-of-the art photochemical kinetics model requires the specification of time-dependant rates for the two most import
