Retrieval source areas producing aerosols arrived in central part of Ukraine using back-trajectory statistics

Abstract

Concentration weighted trajectory method for aerosol sources retrieval technique based on the joint statistical analysis of the aerosol column volume concentrations and back-trajectory data was used to estimate spatial distribution of aerosol sources of particles arrived in the Central Ukraine region and observed at Kyiv site data. The column volume concentration data for Kyiv AERONET network site were used. It was shown that the north-east territories (in relation to Kyiv monitoring site) give small contribution to coarse mode aerosol content. The events of increased coarse mode aerosol concentration have been caused by sources at south-east regions. Fine mode of aerosol particles arrived to the Kyiv station mainly from north and north-eastern territories.
