The presence of complex nature aerosols is a constant phenomenon, and their interaction with solar radiation, earth, and atmospheric gases brings a change in temperature profile, which threats the lives of living organisms on the earth's surface. Urban and industrial emissions are significant contributors to producing aerosols and particulate matter. In all the major cities of Pakistan, the existing concentration of aerosols and ozone with variant values depends on urban and industrial growth, temperature, and amount of received precipitation. Overall southern parts of the country have more concentration of aerosol and ozone than northern parts. MODIS has a wide range of values, and in this study complete range of MODIS Aerosol Optical Depth values was adopted for image analysis. In this regard, data of 10 years from 2011 to 2020 was collected and processed. Images of MOD-08-M3 version 6 were processed, and AOD for each month was retrieved by applying the scale factor approach while through the same process for O3 concentration. O3 values for each month were retrieved. The present study shows the inverse relationship between AOD and O3, which means whenever AOD values increase, O3 values decrease due to seasonal and localization effects.
