Seasonal Dynamics and Temporal Trends of SO₂ Pollution in Tamil Nadu (2024–2025) through Remote Sensing and Geographic Information System
This study investigates the spatial and temporal distribution of sulphur dioxide (SO2) pollution across Tamil Nadu, India, utilizing Sentinel-5P satellite data accessed through Google Earth Engine. Covering the year of 2024 and the initial two months of 2025, the research categorizes SO2 concentrations into distinct seasonal periods: Summer (March–May), Monsoon (June–October), and Winter (November–February), offering insights into spatial and temporal variations in atmospheric SO₂ concentrations, the study aims to generate seasonal SO2 pollution maps to highlight regional hotspots and variations. Furthermore, a time-series analysis will be conducted for the entire 2024-2025 period to identify overarching trends and significant pollution events. The findings revealed high SO₂ concentrations in northeastern Tamil Nadu. Seasonal analysis showed reduced levels during the monsoon due to rainfall cleansing, with a moderate resurgence in winter
