Abstract

The elemental composition of near-surface aerosol in Moscow in the winter periods of 2020 and 2021 are presented according to the data of regular observations of aerosol composition at A.M. Obukhov Institute of Atmospheric Physics RAS. Reliable differences in meteorological conditions (air temperature, wind direction) of these winters are confirmed by statistical tests. The use of statistical methods made it possible to identify groups of elements with similar or opposite indicators characterizing their nature and/or processes forming their concentrations in near-surface air, in particular during the transition period from winter to spring seasons.
