Yom Posted March 26, 2021 Author Share Posted March 26, 2021 Mar 26, 2021 'In SE-Asia the location of fires and the direction of pollution transport varies little year to year ?' Thanks to Laura Kiely et al.: Air quality and health impacts of vegetation and peat fires in Equatorial Asia during 2004–2015 https://iopscience.iop.org/article/10.1088/1748-9326/ab9a6c '... A linear relationship between emission and exposure may not be expected; exposure to PM2.5 and resulting impacts on health depend on the location and magnitude of the emissions, as well as the atmospheric transport of pollution. However, in Equatorial Asia, the location of fires and the direction of pollution transport varies little year to year... ' '... Our work confirms that smoke from Indonesian fires regularly cause substantial impacts on human health across the region...

Yom Posted March 29, 2021 Author Share Posted March 29, 2021 (edited) FlorC - Yesterday and today , cough , cough. Get well soon. Air pollution is a much bigger problem than many think. Well, sometimes kids are playing with the numbers.... It' s not too difficult... Just for fun. This morning the AQI might have been around 150? Or perhaps someone used the wrong model? Here the Rongkwang numbers offered by https://aqicn.org/station/รพ.-ร้องกวาง-จ.-แพร่ Don't worry, Phrae had much better air than an area north of ChiangRai this morning: 7:00 PM2.5 level 230 ug/m3 ~ AQI 280.
