<title>Investigations of microphysical and chemical composition of aerosol in near-water layer of the atmosphere over the White Sea</title>

Abstract

The peculiarities of spatial-temporal variability of the submicron aerosol number density N Σ (cm -3 ), particle size distribution in the diameter range 0.4 to 10 µm, mass concentration of submicron aerosol Ма (µg/m 3 ) and the mass concentration of black carbon (soot, BC) Ms (µg/m 3 ), as well as chemical composition of particles (ion composition of aerosol soluble fraction) in different regions of White Sea are considered in this paper. The effect of continental and marine sources on formation of the near-water aerosol characteristics is estimated.

Black Carbon Sources Constrained by Observations in the Russian High Arctic

“…Based on isotope measurements, one recent observational study suggests that the contribution of gas flaring emissions to BC at Tiksi is lower than estimated by Stohl et al However, new bottom-up inventories , contain gas-flaring emissions that are even higher than those used by Stohl et al For the clarification of the role of gas-flaring emissions, any EBC measurements from regions closer to the oil production facilities of Russia would be extremely valuable. In these regions, BC has been measured only with low time resolution during a few ship campaigns. ,− However, to relate such measurements to particular source regions, measurements with high time resolution are necessary. In a comparison with the few available observations, modeled BC concentrations were found to be too low, but a comprehensive analysis was not possible because of the low time resolution of these measurements.…”
