“…These results confirm the importance of long-range transport to the total mass concentration of OA and eBC not only during high pollution events (e.g. van Pinxteren et al, 400 2019;Petit et al, 2017;Waked et al, 2018). HOA and BBOA are properly depicted by the primary anthropogenic sources of liquid fuel and biomass burning emissions, respectively.…”

“…Not only local sources drive the aerosol particle chemical composition; long-range transport, influenced by air mass origin, also plays an important role in local number size distribution and aerosol particle chemical composition (e.g. van Pinxteren et al, 2016;van Pinxteren et al, 2019;Waked et al, 2018). Therefore, not all the eBC mass concentration has to be linked to local sources, and a significant fraction can be attributed to long-range transport (e.g.…”

Abstract. The identification of different sources of the carbonaceous aerosol (organics and black carbon) was investigated at a mountain forest site located in central Germany from September to October 2010 to characterize incoming air masses during the Hill Cap Cloud Thuringia 2010 (HCCT-2010) experiment. The near-PM1 chemical composition, as measured by an Aerosol Mass Spectrometer (HR-ToF-AMS), was dominated by organics (OA, 41 %), followed by sulfate (19 %) and nitrate (18 %). Source apportionment of the OA fraction was performed using the Multilinear Engine approach (ME-2), resulting in the identification of five factors: Hydrocarbon-like OA (HOA, 3 % of OA mass), biomass burning OA (BBOA, 13 %), semi-volatile-like OA (SVOOA, 19 %), and two oxygenated OA (OOA) factors. The more-oxidized OOA (MO-OOA, 28 %) was interpreted as being influenced by aged polluted continental air masses, whereas the less-oxidized OOA (LO-OOA, 37 %) was found to be more linked to aged biogenic sources. Equivalent black carbon (eBC) measured by a multi-angle absorption photometer, MAAP, represented 10 % of the total PM. The eBC was clearly associated with the three factors HOA, BBOA, and MO-OOA (all together R2 = 0.83). Therefore, eBC's contribution to each factor was achieved using a multi-linear regression model. More than half of the eBC (52 %) was associated with long-range transport (i.e. MO-OOA), whereas liquid fuel eBC (35 %) and biomass burning eBC (13 %) were associated with local emissions leading to a complete apportionment of the carbonaceous aerosol. The separation between local and transported eBC was well supported by the mass size distribution of elemental carbon (EC) from Berner-impactor samples. Air masses with the strongest marine influence based on back trajectory analysis corresponded with a low particle mass concentration (6.4–7.5 µg m−3) and organic fraction (&approx; 30 %). However, they also had the largest contribution of primary OA (HOA &approx; 4 % and BBOA 15–20 %), which was associated with local emissions. Continental air masses had the highest mass concentration (11.4–12.6 µg m−3) and a larger fraction of oxygenated OA (&approx; 45 %) indicated highly processed OA. The present results emphasize the key role played by long-range transport processes not only on the OA fraction but also on the eBC mass concentration and the importance of improving our knowledge on the identification of eBC sources.

“…In both PSCF and CF methodologies, a regular 0.5 o x 0.5 o grid was superimposed to the region encompassing the considered receptor sites and the computed air mass BTs. The 0.5 o x 0.5 o grid latitudes ranged from 37 o N to 69 o N and the longitudes from 26 o W to 31 o E. PSCF and CF methodologies are briefly described in the following sub-sections and in further details in Waked et al (2018).…”

“…These MLA were measured at noon at a comparable site in term of latitude in Germany from 2000 to 2009 by von Engeln and Teixeira (2013). The use of constant MLA from measurements instead of using the variable PBL heights simulated in GDAS fields was preferred as it enables to minimise the excessive removal of nighttime endpoints due to the high uncertainty in the simulatio n of the nocturnal residual boundary layer (Waked et al, 2018). It should be noted that when endpoints were removed for precipitations and altitude, the air mass age of BTs was reduced and became lower than 72h.…”
