The effect of dust on global ultraviolet solar radiation in the range ( 0.290 – 0.385 μm )‎ Reach Basrah City 30.5oN

الملخص EN

In this paper, The global ultraviolet radiation was measured and recorded on an hourly basis in Basrah (latitude 30.5oN, longitude 47.5o E) during the period 1999 / 2000.

The global ultraviolet radiation (U.V) was measured by an Epply ultraviolet radiation (photometer) (0.290 – 0.385um)[1].

Intensity variation of global daily ultraviolet radiation throughout the year and the effect of dust on daily total ultraviolet radiation were investigated.

It was found that the highest ultraviolet radiation levels are received during June and that the daily total ultraviolet is approximately lower by 28.07% during dusty days.

From measurements carried out, it was found that, on average, 3.05% of the monthly – daily global radiation received is ultraviolet radiation.
