Abstract:
Solar UV B Flux measurements have been made at four discrete wavelengths of 290, 300, 310 and 320 nm during and around the solar eclipse day of 24th October 1995. The Diurnal variation of the UV flux has shown the recovery phase, the flux has shown a sharp increase compared to the normal control day values, for about one to two hours depending on the wavelength. The direct solar flux recorded in the visible and near IR wavelengths did not show any such increase, indicating that there could be some atmospheric ozone decrease either at the surface level or in the columnar level leading to an increase in the measured global UV Flux.
