Abstract The features of anomalous Siberian wildfires in 2019 and trends of their changes during 2000–2019 are analyzed on the basis of satellite monitoring data. The average values of wildfire areas; total volumes of CO, CO 2 , and aerosol PM2.5 emissions; and their density (per area unit) in the Siberian Federal District of Russia and its regions are estimated for a 20-year period, as well as the number, radiative power, and spatial distribution of wildfires on the territory of North Eurasia in 2019. In July 2019, the wildfire area in Irkutsk oblast exceeded the average value for the period of 2001–2019 by more than four times, whereas the related total volumes of emissions of CO, CO 2 , and PM2.5 aerosol in June 2019 were five times higher than their average values for this period. The regional weather-climate features of summer 2019 were revealed using on-land observations and reanalysis, in particular, atmospheric blocking, which is related to the formation of extreme regimes of wildfires and floods in adjacent territories of Siberia.

西伯利亚野火卫星监测及其影响：2019年异常特征及20年变化趋势

摘要 基于卫星监测数据，分析了2019年西伯利亚山火异常特征及2000-2019年变化趋势。野火区的平均值；CO、CO 2 和气溶胶 PM2.5 排放总量；20 年俄罗斯西伯利亚联邦区及其地区的密度（单位面积），以及 2019 年北欧亚领土上野火的数量、辐射功率和空间分布。 2019年7月伊尔库茨克州野火面积超过2001-2019年平均值4倍以上，而2019年6月CO、CO 2 、PM2.5气溶胶相关排放总量为5比他们在此期间的平均值高出数倍。
