AB: The Indo Gangetic (IG) basin is one of the largest basins on the Earth where approximately one third (360 million) of the Indian population live. This basin is a highly agriculturally productive and industrial basin, due to this and other anthropogenic activities the pollution level is increasing. The increasing aerosol pollution over the IG basin is especially prominent and has been mapped first time by the ADEOS-Polder data and now the effect of pollution is seen from recent satellites onboard. Evidence suggests that the widespread and persistent nature of the pollution is even modifying the regional weather and climate patterns. In the present paper, we show the trend of air quality parameters measured on the ground and also from the satellites over various cities lying in the Ganga basin. We show the effect on population and increasing vehicles on the air quality of the major cities. Further, we show the influence of pollution on the total ozone concentration. The effect of increasing pollution is clearly seen from the air quality trend and the total ozone content over the major cities over the Ganga basin, on the contrast such effect is not seen over the Indian cities lying in the southern and central parts of India.
