Abstract
Air pollution is an inevitable global problem, harming both humans and the environment. Where pollution from fine particulate matter leads to more than 7 million premature deaths per year. This research quantifies and contrasts the magnitude, duration, and spatial characteristics of air pollution episodes over the North-China and Indo-Gangetic Plains for one entire year, 2019, and puts them into perspective by relating them to the regional anthropogenic emissions, thereby elucidating the role of meteorology in exacerbating or avoiding air pollution episodes in both regions. It does so by utilizing openly available gridded datasets of emissions and pollution concentrations from the European Centre for Medium-Range Weather Forecasts and involves statistical data analysis and visualization using the NCAR Command Language. Pollution forming efficiency was found to be significantly higher over the Indo-Gangetic Plain, especially in the winter months. Although both regions have similar aerosol concentrations, annual anthropogenic emissions are double over the Noth-China Pain. The accumulation potential is too high over the Indo-Gangetic Plain due to local meteorology, which means the region could never follow a similar pathway for development. It is recommended to further study the influence of local chemistry on gas to particle pollution, especially between the post-monsoon and winter months.
