Abstract:
Based on an analysis of the data on temporal variability of the sky background-radiation fluxes in the UV, the aerosol extinction coefficients and the atmospheric meteorological parameters obtained during the morning solar eclipse we have found a significant increase in the UV-radiation level during the period of the first minutes after the solar eclipse termination. This effect is shown to coincide in time with the dissipation of fog formed during the solar eclipse. It is supposed that the increase in the scattered UV-radiation flux recorded immediately after the eclipse is due to an addition of the single-scattered direct solar radiation by the particles of the dissipating fog when its vertical optical thickness approaches unity. The estimates presented show that the morning fog formation on the 9th of March was most likely caused by the solar eclipse.
