Abstract 70 ± 2.7  %), whereas RWC (22 ± 2.7  %) was more abundant than WF (8.0 ± 2.9  %). Modeled BC concentrations from FLEXPART (FLEXible PARTicle dispersion model) attributed an almost equal share to FF sources (51 ± 3.1  %) and to biomass burning. Both FLEXPART and the PMF analysis concluded that RWC is a more important source of (e) BC than WF. However, with a modeled RWC contribution of 30 ± 4.1  % and WF of 19 ± 2.8  %, FLEXPART suggests relatively higher contributions to eBC from these sources. Notably, the BB fraction of EC was twice as high as that of eBC, reflecting methodological differences between source apportionment by LHS and PMF. However, important conclusions drawn are unaffected, as both methods indicate the presence of RWC- and WF-sourced BC at Zeppelin, with a higher relative BB contribution during the non-heating season. 281 ± 106  ng m- 3 10, although surpassed by sea salt aerosol (682 ± 46.9  ng m- 3 613 ± 368  ng m- 3 4 2 - (314 ± 62.6  ng m- 3), originating mainly from anthropogenic sources in winter and from natural sources in summer.
