      abstract     = {We report source specific isotope ratios of levoglucosan,
                      the specific biomass burning tracer, in aerosol particle
                      from the combustion of selected woods used for domestic
                      heating in Europe, of coals containing cellulose (lignites)
                      as well as of corn, a C4 plant. Here, we combine compound
                      specific δ13C measurements of levoglucosan with total
                      carbon δ13C of parent materials, to assess isotopic
                      fractionations due to biosynthetic pathways or combustion
                      processes. Levoglucosan formed during the combustion of
                      cellulose from coals shows with δ13C of −21.1‰ and
                      −18.6‰ a moderate enrichment in the heavier isotope
                      compared to the C3 plant samples. Contrarily, observed
                      levoglucosan isotope ratios of −25.0 to −21.5‰ for C3
                      plant samples are significantly lower than for the C4 plant
                      sample (−12.4‰), as expected from the stronger 13C
                      discrimination during the carbon fixation process by C3
                      compared to C4 plants. Overall, the C4 plant sample shows a
                      13C enrichment in all bulk measurements, on average by
                      12.2‰, 14.2‰ and 14.2‰ for total carbon (TC) in
                      aerosol particle, whole plant/coal material and cellulose
                      samples, respectively. Further, δ13C measurements of
                      levoglucosan and TC of biomass burning aerosol particles,
                      bulk plant/coal and cellulose in C3 plant samples agree well
                      with the published observations. The combined
                      levoglucosan/TC isotopic analyses can be used to
                      differentiate among C3/coal/C4 origin of the smoke emissions
                      from the cellulose-containing-fuel combustion. Noticeably,
                      there is a consistent δ13C offset between C3 plant material
                      and levoglucosan, which allows deriving emission
                      levoglucosan isotope ratios when the combusted plant types
                      are known.},
