Stubble-burning in northern India is an important source of atmospheric particulate matter (PM) and trace gases, which significantly impact local and regional climate, in addition to causing severe health risks. Scientific research on assessing the impact of these burnings on the air quality over Delhi is still relatively sparse. The present study analyzes the satellite-retrieved stubble-burning activities in the year 2021, using the MODIS active fire count data for Punjab and Haryana, and assesses the contribution of CO and PM from such biomass-burning activities to the pollution load in Delhi.

- The pandemic lockdowns allowed researchers to assess how reduced emissions impacted air quality across different locations, analyzing pollutants like PM10, PM2.5, NOx, CO, and ozone (O) at various stations.
- Major differences in pollutant levels were noted in specific cities, with Delhi experiencing significant reductions in PM2.5, NO, and CO during lockdown while rural areas like Mahabaleshwar showed minor changes and even an increase in ozone levels.
- The findings suggest that air quality improvements depend on the type of pollutants dominating each region, with recommendations for targeted emission controls to enhance air quality across various locations.
