| Abstract: | The present study was
mainly confined to the investigation of the responses of downwelling solar
radiation fluxes in ultraviolet wavelengths to the partial solar eclipse event
on 22 July 2009 besides an investigation on sferics at 27 kHz. The measurements
were done at ground-based station of Kalyani (22°58'N, 88°28'E) where the maximum
solar coverage was more than 90%. The optical properties and associated
meteorological parameters are simultaneously examined. During the partial solar
eclipse, UV components of sunlight reaching the Earth’s surface were found to
decrease significantly in addition to luminosity. The surface air temperature
was dropped but relative humidity was increased. A characteristic short period
fading was also recorded at 27 kHz. The results have been interpreted by
considering the impacts of solar eclipse on UV radiation and ionospheric
propagation. |
