Spatio-Temporal Monitoring of Atmospheric Pollutants Using Earth Observation Sentinel 5P TROPOMI Data: Impact of Stubble Burning a Case Study

The problems of atmospheric pollutants are causing significant concern across the globe and in India. aggravated level surrounding environment poses serious threats to normal living conditions by deteriorating air quality adverse health impacts. Pollutant concentration increases during harvesting seasons Kharif/Rabi due stubble burning is other points or mobile sources. present study intended monitor spatio-temporal variation major using Sentinel-5P TROPOMI data through cloud computing. Land Use/Land Cover (LULC-categorization classification human activities natural coverage on landscape) was utilised extract agricultural area site. It involves computing MOD64A1 (MODIS Burned monthly gridded data) (S5P Tropomi) for pollutants, such as CH4, NO2, SOX, CO, aerosol, HCHO. burned output provided information regarding period, which has seen post-harvesting residue after Kharif crop (i.e., rice from April June) Rabi wheat September November). long duration farmers’ stubble/biomass remains field successive crops. This period used criteria considering results showed a increase SO2, aerosol AMJ months (stubble crops) OND each year. validated with ground control station PM2.5/PM10. patterns precipitation temperature-gridded datasets. trajectory frequency mass movement HYSPLIT model that highest were observed months, followed year (2018, 2019, 2020, 2021). supports role robustness Earth observation evaluate distribution.
