Farm Fires in Punjab Severely Undercounted, Contributing to Toxic Smog
Farmers reportedly adjust stubble burning times to evade NASA satellite detection, prompting India to adopt new monitoring methods.
- Satellite data reveals significant undercounting of farm fires in Punjab due to farmers timing burns outside NASA satellite overpass windows.
- Stubble burning remains a major contributor to hazardous air quality in Delhi and the Indo-Gangetic plain, with AQI levels reaching 'severe' this month.
- India plans to shift from monitoring live fires to analyzing burnt areas, with a new protocol developed by the national space agency currently under testing.
- Experts highlight the role of thermal inversion and aerosols in trapping pollutants, exacerbating smog and reducing visibility in the region.
- Despite government subsidies for alternative methods, many farmers continue crop burning due to high equipment costs and limited availability.
