Air pollution status of Tamil Nadu using geospatial technology

Air pollution is a critical environmental issue that poses significant health risks and impacts the ecosystem, particularly in rapidly developing regions like Tamil Nadu, India. This study, titled "Air Pollution Status of Tamil Nadu using Geospatial Technologies" aims to analyze the spatiotemporal distribution and dynamics of key air impurities, including nitrogen dioxide (NO₂), sulfur dioxide (SO₂), carbon monoxide (CO), particulate matter (PM10 and PM2.5), and ozone (O₃), over the state of Tamil Nadu. Using advanced remote sensing data from the Sentinel-5P satellite, the study analyzes air quality patterns from 2020 to 2024. We employ geographic information systems (GIS) and Google Earth Engine to process and visualize large-scale atmospheric data, identifying pollution hotspots, seasonal trends, and the impact of urbanization and industrial activities on air quality. The study also examines the correlation between air pollution levels and public health indices, providing valuable insights for policymakers. By integrating air quality data with socio-economic and environmental factors, this research contributes to a more suitable understanding of air pollution dynamics in Tamil Nadu, offering a comprehensive framework for mitigating the adverse effects of air pollution in the region.
