Based on data of direct solar radiation observations during the years of 1959-1970 in five locations, the variation in atmosphericturbidity coefficients is estimated.
基于1959—1970年五个站太阳直射辐射的观测资料对大气浑浊系数的变化作了评价。

The calculation results show that the ultraviolet radiation received at the ground is more sensitive to changes in atmosphericturbidity than changes in the total ozone amount.
It is found that Agung's and several other volcanic eruptions have increased the atmosphericturbidity after the autumn of 1963, especially during the autumn and winter seasons.
