✦ Synopsis

Ozone (0,) is one of the most important minor components of the troposphere and stratosphere. It is involved in the attenuation of the solar flux in the visible and ultraviolet regions and in many photochemical processes. Accurate calculations of the atmospheric transmission and photolysis frequencies require laboratory values of the absorption cross sections uo, in the temperature range 200-300 K, such values are reported. Measurements of the absorption cross sections of 243 and 295 K in the range 195-345 nm and at 213 O3 have been made at four temperatures 2 18, 228, K in the range 300-345 nm.
