“…In the study [7] a combination of ground-base d and satellite observations was used to investigate diffe rent sources of aerosol loadings over Lithuania during two different time periods. The negative carbon iso topic mean value (-30.9 ± 0.2‰) during 31 March-2 April 2008 obviously indicates that a major part of carbon mass in aerosol particles transferred by the continental air masses is from wildfire location.…”

“…Different aerosol sources have a specific stable carbon isotopic composition ( 13 C/ 12 C). The δ 13 C of total carbon (TC) has been successfully used to identify the origin of pollution sources (Widory et al, 2004;Kelly et al, 2005;Ulevicius et al, 2010) and to assess the anthropogenic input (Górka et al, 2009;López-Veneroni, 2009;Górka et al, 2012). Therefore, it is often difficult to distinguish fossil, biogenic and biomass burning emissions by measuring δ 13 C of TC alone, due to overlapping δ 13 C values between major pollution sources such as fossil and nonfossil fuel burning emissions (Cao et al, 2011;Kundu and Kawamura, 2014).…”

We applied stable carbon isotope ratio ( 13 C/ 12 C) and radiocarbon ( 14 C) analysis for the quantification of three main aerosol sources (coal, biomass and liquid fossil fuel derived aerosol emissions). Submicron aerosol samples (PM 1 ) were collected from 27 th October, 2014 to 19 th January, 2015 at a suburban site of Vilnius city (Lithuania). To determine fossil and non-fossil contributions to submicron carbonaceous aerosol particles, 14 C measurements of total carbon (TC) were performed using single stage accelerator mass spectrometer (SSAMS, NEC, USA). The concentrations of TC and δ 13 C in PM 1 fraction were measured using elemental analyzer interfaced to isotope ratio mass spectrometer (EA-IRMS).The TC concentration during measurement period ranged from 1.3 to 9.6 µg m -3. The variation of TC concentrations can be explained by the influence of long-range transport and dispersion properties of the boundary layer (mixed layer depth).We found that biomass-derived aerosol sources are prevailing in Vilnius during wintertime and ranged from 57% to 84% of total carbonaceous aerosol fraction. Applying isotope mass balance calculations the traffic emissions were estimated to be 15 ± 7% and coal combustion made up 14 ± 9% in PM 1 . To provide better information about the pollution sources, the carbon isotope analysis along air mass transport pattern was performed. Our results demonstrated that the high contribution to PM 1 from coal burning (up to 40%) was observed for air masses transported from highly industrialized Western Europe regions. Combination of stable carbon isotope ratio with the radiocarbon data allow to distinguish coal from liquid fossil fuel in the aerosol particle emissions.

“…Bergstrom et al (2007) report α ABS for emissions from biomass burning ranging from 1 to 3. A value of 2.0 ± 0.4 is observed by Ulevicuis et al (2010), Kirchstetter et al (2004) report 1.8 for a savannah fire. Sandradewi et al (2008) suggest an absorption exponent of 1.8-1.9 to be indicative for aerosols originating from domestic wood burning.…”

A period of increased particulate matter concentrations was observed at the high-altitude Sonnblick Observatory in August 2013. Trajectory analysis, wildfire maps and the evaluation of aerosol measurements revealed a combined and sometimes alternating influence of long-range transport of Saharan dust and emissions of wildfires. The occurrence of Saharan dust was confirmed by an increase of coarse particle number concentration and a negative exponent of the single scattering albedo wavelength dependence, determined by Nephelometer and Aethalometer measurements. During time periods less influenced by Saharan dust, number concentration of accumulation mode particles increased and a marked correlation of aerosol mass concentrations and CO mixing ratios was observed. By analyzing the wavelength dependence of the absorption coefficients determined with a seven wavelength Aethalometer, the influence of the two aerosol sources was decoupled. Therefore, absorption exponents of 3 and 1.3 were assumed for Saharan dust and wildfires, respectively. Mass concentrations of particulate matter caused by Saharan dust and wildfire emissions were estimated, with the contribution of Saharan dust to overall particulate matter mass ranging from 5% to 80%.
