Abstract:

In this paper we present some results of monitoring the total solar radiation, which is being performed at the TOR station of IAO SB RAS since April 1995. Some results of evaluation of the radiation regime nearby Tomsk have been verified by the comparison with the actinometric data of Ogurtsovo station. We have revealed that during the period of the study quite steady radiation regime with maximum of incoming solar radiation in July was observed. The amount and variation range of the monthly mean solar radiation varied depending on the season. During wintertime the coefficient of variation of the monthly mean radiation varied within 5 to 9% and from 2 to 24% during transition periods. The amount of solar radiation income depending on air mass type and synoptic condition has been investigated. The complex dependence is observed of the income of solar radiation during a year on the type of air mass that reflects the peculiarities of the general circulation of the atmosphere over the region. During other periods diurnal solar radiation sums are 1.8 times larger at the presence of anticyclones.
