تطبيق تقنية الاستشعار عن بعد لتحديد تباين تلوث الهواء بالهباء الجوي في منطقة أبها الحضرية

الملخص EN

The research aims to detect dust pollution in the urban area of Abha, monthly and annually, by deriving the layers of atmospheric pollution resulting from dust storms from remote sensing data, and it will be followed by a spatial analysis using geographic information systems to integrate the information layers, and to predict the pattern of distribution and spatial changes between a month Finally, the results of the research found that there is a spatial variation in the distribution of dust pollution levels from month to month, and there are specific areas where some pollution levels are almost constant in different months, and the results of the detection of air pollution with dust in the region confirm the prevalence of moderate dust spreading over an area It amounted to 2506.2 km2, with a rate of 96% of the total area of the region, and it covers the eastern, southeastern and northwestern Abha metropolitan area, followed by the area that suffers from heavy dust spreading with an area of 60.3 km2, or 2.3% of the total area of the region, and it is located in the center, north, west and southwest The urban area of Abha, and then came the area where the dust is lightly distributed, with an area of 44.1 km2, which is 1.7% of the total area of the region, and appears northwest, center and southwest of the Abha urban area.
