A Photochemical Theory on the Formation of Ozone in the Atmosphere

[摘要] The authors have assumed the fundamental reaction of formation and decomposition of ozone as follows: formation; decoposition; Where M means any molecule or atom in the atmosphere. From the above reactions the formula of the photochemical equilibrium of ozone and oxygen has been deduced. in which K is an equilibrium constant, P the atmospheric pressure at the height h above the ground, α and β the absorption coefficients of ozone ánd oxygen, q and q' the number of light quanta to produce excited oxygen molecules and to destroy ozone respectively.In the next place, we put, where, q0λ, and q0λ' are the number of light quanta coming into the atmosphere which is calculated under the assumption that the sun is a black body of 6000°K. αq and βq' at each height are calculated by the graphical integration with regard to the wave lepgth. Since the distribution of ozone is unknown, we put _??_. The relation between x and h can be deduced by the formula of equilibrium. The results are shown in Fig. 3 and Fig. 4, which are in good agreement with observations. The maximum absorption of the ultra-violet ray occurs at about 40 km at which it is expected that the remarkable elevation of temperature would begin.
