摘要：

The anomalous vertical distribution of organic aerosol recorded on September 14, 2018, is analyzed on the basis of aircraft sounding data. It is anomalous in that, in contrast to the long-term average profile, the maximal concentration in the boundary layer during this flight was more than an order of magnitude higher than the previously measured concentrations. The contribution of aerosols of different origins to the total concentration in different tropospheric layers is estimated. The analysis of possible sources of aerosol precursors revealed quite a wide sector, on the territory of which there are boreal forests, which are sources of biogenic compounds, and objects of industrial infrastructure, which are sources of anthropogenic emissions.
