  2. November 27 - 18:00 Phrae AQI 33, but 20 km north: AQI 137 **************
  3. absolutly different, sorry. this too Thanks. But some people can't. Never.
  4. I want the OP reduced to the most important. What a tragedy. One man dead, the other in prison. And two families mourning. May be helpless? No future. Why? I could aqlso add e.g. 'The Plague and the Promise in Thai Rice', this was 2017 ... or http://www.indexmundi.com/de/rohstoffpreise/?ware=reis&wahrung=thb ... but I am more inclined to pity the dead. And also with the man who caused it. ***************************
  5. November 26 - 12:00 CM - CR - Lampang **********************
  6. Masks - PM2.5 - Covid ... it is reasonable to consider China KN95, AS/NZ P2, Korea 1st Class, and Japan DS2 FFRs as “similar” to US NIOSH N95 and European FFP2 respirators, for filtering non-oil-based particles such as those resulting from wildfires, PM 2.5 air pollution, volcanic eruptions, or bioaerosols (e.g. viruses). (see also attached PDF) ******************** Comparison_FFP2_KN95_N95_Filtering_Facepiece_Respirator_Classes_rev4.pdf
  7. November 25 - 12:00 Most of Isan and the Eastern Seaboard green. https://aqicn.org/here https://www.ventusky.com/ https://www.windy.com/ ********************
  8. November 24 - 20:00 Bad tonight - CM and CR worse than BKK ***********
  9. November 24 - 11:00 Green north of Phrae, a happy day Chiang Mai Chiang Rai *************************
  10. Something is wrong with this? At least it would be a start. Then, one quarter of the 'ordinary' air pollution might come from burning sugar cane or rice stubbles. - So, trash burning, Industries and flying in PM2.5 pollution, all this too, only oen quater? Maths is difficult.
  11. November 23 - 17:00 In the garden, different places: PM2.5 93 / 173 / 197 AQI 170 / 223 / 247 People with respiratory or heart disease, the elderly and children should avoid any outdoor activity; everyone else should avoid prolonged exertion. **********************
  12. November 23 - 16:00 North of Phrae was not too bad, but now 89ug/m3, that's AQI 168. - Apart from that yellow/orange. But ' Once the lungs are damaged by fine dust, they can hardly defend themselves against SARS-CoV-2.
