Peak #ArcticFires activity seems a long time ago but Sakha Republic & Chukotka🇷🇺still experiencing above average daily total #wildfire intensity for late August in #CopernicusAtmosphere GFAS data to 24/08. #TerraMODIS🛰️imagery shows continuation on 25/08 ImageImageImageImage #Wildfire activity in other parts of #Siberia has been relatively low all summer. Krasnoyarsk & Irkustk have been experiencing increased daily total intensity over last 2 weeks close to 2003-2018 mean & << 2019. ImageImage
