Variability of surface solar irradiance and aerosol optical depth during partial solar eclipse of January 4, 2011 in Kishinev, Moldova

Variation of surface solar irradiance and aerosol optical depth (AOD) during the partial solar eclipse on January 4, 2011 is analyzed on the basis of the ground observations at the Kishinev (Chisinau) site. Maximum of magnitude of the eclipse obscuration was 0....
