Ground-based observation of shortwave solar radiation during solar eclipse on october 3, 2005 in Chisinau, Moldova

Abstract

The influence of partial annular solar eclipse observed during October 3, 2005 onto the variation of shortwave downwelling solar irradiation at the Chisinau site is analyzed. Evaluation of the components of broadband solar radiation from UV-B to near IR falling onto the Earth’s surface is presented. Such type of dimming was due to partial annular solar eclipse event with maximum phase of 40%, which resulted in 3.4- 4.5% reduction of daily totals of shortwave downwelling solar radiation.
