Abstract

The Arabian Gulf has been identified as a world third largest source of dust which is mostly active during spring and summer. The United Arab Emirates (UAE) lies on the eastern coast of the Arabian Peninsula where 80 percent of the UAE land occupied by desert and makes it more susceptible to release large amount of dust aerosols during dust storms. The fine dust particles raised by the wind usually stays in the air for weeks and travel for thousands of kilometer. The presence of the dust in the atmosphere for a significant period of time is considered a natural hazard that has several effects on climate, air quality and solar energy production. In the past decade, significant researches were conducted in monitoring environmental changes using remote sensing techniques including dust storms detection. In this paper, a neural-networkbased model was developed to estimate AERONET Aerosol Optical Thickness (AOT) over land areas as an indication of dust and generate real time visualization of dust concentration over the UAE using SEVIRI data. A high correlation between combinations of SEVIRI and AERONET AOD was found as proof that SEVIRI channels can be used to quantify dust information. In addition, the visualization model showed that the diversity of the characteristics of land cover in the UAE was creating a confusing in detecting dust and more diverse ground measurement needed.
