Context: Stubble burning in Punjab and Haryana heavily pollutes NCR air. While satellites monitor fires, farmers burning outside detection windows raise concerns about tracking methods and government measures.
About Satellites Used to Track Stubble Burning:
- NASA Satellites:
- Aqua (2002) and Suomi-NPP (2011) with MODIS and VIIRS instruments detect fires via visible and infrared imaging during overpasses at 1:30 p.m. and 1:30 a.m. local time.
- Ozone Mapping and Profiler Suite measures aerosol levels to assess smoke impact on air quality.
- South Korea’s GEO-KOMPSAT 2A:
- Provides continuous geostationary observations to capture fires missed by Aqua and Suomi-NPP.
- European Space Agency’s Sentinel II:
- Offers burnt area data every five days.
- Indian Satellites:
- INSAT-3DR: Tracks fire activity but with coarse resolution, limiting accuracy.
- RESOURCESAT Series: LISS-3, LISS-4, and AWiFS sensors detect fires with varying spatial resolutions.
