October 8, 20205 yr Author October 8 The 2019-2020 bushfires in New South Wales (NSW) have been unprecedented in their extent and intensity. The dust traveled to South America, more than 15,000 km. In September 2020, historic wildfires on the U.S. West Coast lofted plumes of smoke high into the atmosphere. Pushed by prevailing winds that sweep air from west to east. Leipzig, Germany: 11./12.09.20. The consequences of the massive forest fires on the US west coast can also be felt in Europe: smoke from California has been pouring over Germany since Friday morning. Measuring devices from the Leibniz Institute for Tropospheric Measurement (TROPOS) show a layer of dust that has been floating over Leipzig since 6 a.m. on Friday. During the course of Friday and Saturday the shift decreased from 10 to 12 to 5 to 10 kilometers in height. The layer of smoke continues on Monday. It has now fallen to around 4 kilometers. ****************************************************** What is PM? PM stands for particulate matter (also called particle pollution): the term for a mixture of solid particles and liquid droplets found in the air. Some particles, such as dust, dirt, soot, or smoke, are large or dark enough to be seen with the naked eye. Others are so small they can only be detected using an electron microscope. PM10 : inhalable particles, with diameters that are generally 10 micrometers and smaller. PM2.5 : fine inhalable particles, with diameters that are generally 2.5 micrometers and smaller. How small is 2.5 micrometers? Think about a single hair from your head. The average human hair is about 70 micrometers in diameter – making it 30 times larger than the largest fine particle. https://www.epa.gov/pm-pollution/particulate-matter-pm-basics **************************

October 17, 20205 yr Author October 17 https://tna.mcot.net/english-news-563784 - also: Bangkok governor Aswin Kwanmuang said he discussed fine dust solutions ... as the pollution of particulate matter 2.5 micrometers and less in diameter (PM2.5) would normally return from December due to stagnant air. This is interesting: ' PM2.5 resulted from many factors including vehicles, burning and construction ' What will be done? * ban vehicles with six wheels or more from entering inner Bangkok between 6am and 9pm from December to February to reduce vehicle emissions. * school management would be advised to suspend outdoor activities from December to February and close schools if severe fine dust pollution continues for longer than three days * Outdoor construction would be suspended during thick PM2.5 conditions * Dust control measures would also cover the hospitals and hotels that used boilers So, everything will be fine. Today in Thailand good and fresh air, except some places in Bangkok. The Future? Nobody knows. ventusky.com *************************** Confirm: aqicn.org **************** Edited October 17, 20205 yr by Yom
