Effect of the Scattered Solar Radiation on the Atmospheric Ozone Measurements

Abstract

The spectrometer-ozonometer was used for measurement of radiation atnine wavelengths in the ultraviolet range to register the passed solarradiation. The applicability limits of the Lambert’s law for the calculationof atmospheric ozone content by the multi-wavelength method were studied.It was found that the deviations from this law which allow to use thestandard method only under solar zenith angles below 80° were due to thelight scattering processes. A model proposed in this work made it possible totake into account the light scattering processes, which become importantunder oblique beam propagation. The model was compared with thecalculations on the basis of the multi-wave method. The reflectioncoefficients for several wavelengths were calculated using the four-fluxmodel.
