The quantum yield for O(1D) production in the photolysis of ozone in the ultraviolet region as a function of wavelength and temperature is a key input for modeling calculations in the atmospheric chemistry. To provide the modeling community with the best possible information, the available data are critically evaluated, and the best possible recommendations for the quantum yields are presented. Since the authors of this paper are the principal investigators of the groups which have provided most of the recent experimental data for the O(1D) quantum yields, the basic assumptions made by each group, the input parameters used in obtaining the quantum yields, and possible sources of systematic errors are well examined. The fitting expression of the O(1D) yield as a function of photolysis wavelength λ and temperature Tis presented in the ranges of 306 nm ≤ λ ≤ 328 nm and 200 K ≤ T ≤ 300 K. The recommendation values of the O(1D) quantum yield for 290 nm ≤ λ ≤ 306 nm and 328 nm ≤ λ ≤350 nm are also presented. The formation mechanisms of O(1D) in the photolysis of ozone which result in the wavelength and temperature dependence of the O(1D) yields are interpreted.
