Studying the effect of aerosols on air temperature in Basra city

Abstract EN

In research we study the effect of Aerosols that created in the atmosphere from natural or anthropogenic origin which represent a very large diversity in size and chemical composition.

Aerosol has significant environmental, health and climatic effects that affect the balance of earth radiation and the quantity of radiation arrival the Earth's surface, as well as its indirect effect in the process of nucleation and formation of clouds.

The variation in the temperature and Aerosol optical depth (AOD) of Basra for the period 2003-2015 was analyzed and then the relationship between them was established using the MODIS sensor for the Aqua satellite.

The highest average value of seasonal AOD was recorded in spring and summer, with the maximum values at (0.43-0.46), while the lowest values were (0.33-0.34) in the winter and autumn.

The results showed that Diurnal Temperature Range (DTR), maximum, minimum, and mean air temperature are correlated with AOD strongly.
