علاقة شفافية الغلاف الجوي بقيم الأشعة فوق البنفسجية الواصلة لمحطات الموصل، بغداد و البصرة

Abstract EN

The research aims to determine the relationship of air transparency with the values of ultraviolet rays arriving at the study area (Mosul, Baghdad and Basra) and the effect of air clarity on the values of ultraviolet rays arriving at the study area.

as the transparency of the atmosphere was calculated by a mathematical model, and a mathematical model was also relied on to calculate the values of ultraviolet rays reach to the earth surface, by making a correlation between air transparency and ultraviolet rays based on the (SPSS) program to find out the extent of the relationship between them.

The research found that the values of atmospheric transparency vary in the study area, where the stations (Baghdad and Basra) recorded the highest annual rate of air transparency, which amounted to (0.45), while the Mosul station recorded the lowest values of transparency, where the annual rate was about (0.43), and from This shows that the values of atmospheric transparency rise as we go from north to south in the study area.

The research also showed that the study area enjoys a good percentage of transparency that allows most of the solar radiation to pass through the atmosphere and reach the surface of the earth (the study area).

The study, as the study showed that the transparency and purity of the atmosphere have a significant impact in determining the values of ultraviolet radiation.
