Abstract
The homogeneous removal rate of sulfur dioxide from the lower atmosphere of Central Europe has been calculated on the basis of the photophysical data of SO2 within its absorption bands (2900 -4000 Å) and the measured monochromatic actinic irradiance (solar quantum flux) in Central Europe. The maximum rate of the sunlight-induced photooxidation during the summer was found to be 0.25% per hour. The results are compared with those obtained from experiments in simulated and real atmospheres.
