Satellite data helps cut PM2.5Listen to this articleSatellite-driven pollution models are delivering tangible gains in the fight against PM2.5, reducing fire hotspots and burned areas in pilot provinces and underscoring the role of data and technology in improving air quality, according to the Thai Health Promotion Foundation (ThaiHealth). Presenting the findings at the Thailand National PM2.5 Forum #2 yesterday, ThaiHealth deputy chief executive Dr Pairoj Saonoum said the project combined satellite data with rapid local response to suppress forest fires and prevent agricultural burning. When burning is detected, Dr Pairoj said that local teams are immediately deployed to contain fires and halt further ignition. Burned areas fell by 20–30%, while downstream PM2.5 levels dropped by about 10%. He said the success highlights the importance of turning existing data into action, noting that this year, the satellite-based model will be expanded to six upper northern provinces.
