Siberian wildfire smoke causes PM levels to rise in some parts of Mongolia www.montsame.mn

Due to winds blowing from the north, clouds of smoke from the Siberian wildfires in Russia reached the central and eastern regions of Mongolia on August 4. With the air quality noticeably degrading from about 3 pm on August 4, the smoke began to clear out during the afternoon of the next day on August 5.
Air quality monitoring stations in Ulaanbaatar have detected that the average concentration of PM10 micro particles per hour reached 168 mkg/m3 during night time, with PM2.5 reaching 103 mkg/m3 as a result.
The hourly average concentrations of fine particulate matter was 38-69 mkg/m3 on August 4, which is 4-10 times more than the previous day, reported the National Agency of Meteorology and Environment.
However, the wildfire smoke entered the territory of Mongolia once again on August 7, reaching the capital city around midnight. The European Union’s Copernicus Atmosphere Monitoring Service (CAMS) website shows that the smoke is forecast to cover the central and eastern regions of the country until the middle of next week.
