Conditions influencing incoming global solar radiation in Hornsund (Spitsbergen) in spring 2015
Abstract This article analyses the conditions affecting the incoming global solar radiation in Hornsund (Spitsbergen) in spring of 2015. Incoming solar radiation turned out to be average for the season under analysis, as compared with longer-term data. The clearness index ( K T ) was 0.46, and was m...

Incoming solar radiation turned out to be average for the season under analysis, as compared with longer-term data. The clearness index ( K T ) was 0.46, and was mainly determined by the extent of cloudiness. As a result of differences in the length of day, sunshine duration in May was greater than in April. Incoming solar radiation to the earth’s surface is also affected by the atmospheric optical properties. The average value of aerosol optical depth (AOD) at 500 nm in Hornsund in spring of 2015 was 0.087. In the analysed period, increased values of AOD at 500 nm (up to 0.143) were observed, although these are not record values. Over April and May, the greatest part of optical depth was comprised of anthropogenic aerosols (41%), followed by marine aerosols (26%), desert dust (21%) and biomass-burning aerosols (12%). This indicates the significant role of the anthropogenic factor in the climatic conditions of Spitsbergen.
