Estimating aerosol optical depth (AOD) seasonal variability in Pakistan by using MISR
Abstract
Estimation of aerosol optical depth is an important phenomenon to determine the environment pollution, determine climate change and to mitigate air borne diseases in all regions of Pakistan. For an estimation of aerosols optical depth, related data is downloaded from the National Aeronautics and Space Administration (NASA)-World View of two different months of the same year i.e. 1st January 2017 for winter in Pakistan and 1st May 2017 for summer in Pakistan. After the images acquisition, further application of Geographic Information System (GIS) has been applied to generate the maps and results is analyzed for the said months. It has been observed by analysis that during the winter season the value of Aerosol optical depth (AOD) is increased up to 2.29 in Pakistan which means that aerosols are dense in number and during summer the value of Aerosol optical depth (AOD) is approximately 0.44 which is less than winter value because air masses travel only short distances in summer and cause the less concentration of aerosols. So, it is necessary to take effective steps to control and overcome the winter concentration of aerosols which becomes the main cause of urban haze, smog, pollution along with hazardous effects to human health like respiratory diseases and eye infections.
