Abnormal vertical distribution of organic aerosol over the south of Western Siberia in September 2018
The abnormal vertical distribution of organic aerosol recorded on September 14, 2018, is analyzed on the basic of aircraft sounding data. The anomaly is that, unlike the long-term average profile, this flight has shown a maximal concentration in the boundary layer, which is more than an order of magnitude higher than the previously measured concentrations. The analysis of possible sources of aerosol particle precursors revealed a fairly large sector, in the territory of which there are boreal forests, which are sources of biogenic compounds, and objects of industrial infrastructure, which emit anthropogenic compounds.
