Estimation of Spatial Distribution of Potential Sources of Carbonaceous Aerosol from Local Measurements near St. Petersburg
Abstract
The results of a back-trajectory analysis of 9-year (2013–2021) measurements of organic (OC) and elemental (EC) aerosol carbon concentrations made at the atmospheric monitoring station near St. Petersburg (Peterhof, 59.88° N, 29.83° E) are presented. The spatial location of sources was estimated by the concentration weighted trajectory (CWT) method in the geographic area 16°–44° E × 48°–68° N. The data allow us to identify the territories with the strongest OC and EC emissions and estimate the seasonal variability of these emissions. In particular, the estimates show that the most intense sources of OC and elemental aerosol carbon in the studied region are located in the Volga-Oka interfluve and on the adjacent territories. It is demonstrated that linear regression coefficients between CWT function values for OC and EC differ for different regions and seasons and may indicate the prevailing type of sources of carbon-containing aerosol particles.
