Abstract

Seasonal variation of the ground reaching global UV-B flux at a low latitude non-industrial location Mysore (12.6°N, 76.6°E) is examined in comparison with the seasonal variation of atmospheric ozone data from the Dobson spectrophotometer operated at Kodaikanal (10.2°N, 77.5°E). The observed dissimilar variation of the global UV-B flux with ozone for different solar zenith positions indicates the role of seasonally varying atmospheric aerosols and particulate in producing enhanced scattering of UV-B radiation in summer period. Monthly variation of atmospheric turbidity coefficient β also indicates the seasonal variation of the atmospheric aerosol and particulate concentrations which are larger for the summer months.
