Using Aerosol Light Absorption Measurements for the Quantitative Determination of Wood Burning and Traffic Emission Contributions to Particulate Matter
J. Sandradewi,André S. H. Prévôt,Sönke Szidat,N. Perron,M. Rami Alfarra,V. A. Lanz,Ernest Weingartner,Urs Baltensperger +7 more
TL;DR: A linear regression model of the carbonaceous particulate mass in the submicrometer size range CM(PM1) as a function of aerosol light absorption properties measured by the aethalometer is introduced, and results indicate that light absorption exponents of 1.8-1.9 for wood burning calculated from the light absorption at 470 and 950 nanometers should be used to obtain agreement of the two methods regarding the relative wood burning and traffic emission contributions.
Journal ArticleDOI
Identification of the mass spectral signature of organic aerosols from wood burning emissions.
M. Rami Alfarra,André S. H. Prévôt,Sönke Szidat,J. Sandradewi,Silke Weimer,V. A. Lanz,Daniel Schreiber,Martin Mohr,Urs Baltensperger +8 more
TL;DR: The identified ambient signature of wood burning was found to be very similar to the mass spectral signature obtained during the burning of chestnut wood samples in a small stove and also to the spectrum of levoglucosan.
Journal ArticleDOI
A study of wood burning and traffic aerosols in an Alpine valley using a multi-wavelength Aethalometer
J. Sandradewi,André S. H. Prévôt,Ernest Weingartner,R. Schmidhauser,Martin Gysel,Urs Baltensperger +5 more
TL;DR: In this article, the authors present a study of aerosol light absorption using a multi-wavelength Aethalometer (λ =370-950-nm) in an Alpine valley where the major local emissions of aerosols in winter are from domestic wood burning and traffic.
Journal ArticleDOI
Dominant impact of residential wood burning on particulate matter in Alpine valleys during winter
Sönke Szidat,Sönke Szidat,André S. H. Prévôt,J. Sandradewi,M. Rami Alfarra,Hans-Arno Synal,Lukas Wacker,Urs Baltensperger +7 more
TL;DR: Aerosols from wood burning versus other sources, particulate matter was collected at two Swiss Alpine valleys during winter. as mentioned in this paper showed that 88% and 65% of the total carbonaceous matter (including all other atoms than carbon) originated from non-fossil sources inside and outside of the village, respectively, which was mainly attributed to wood burning.

Comparison of several wood smoke markers and source apportionment methods for wood burning particulate mass
J. Sandradewi,André S. H. Prévôt,M. R. Alfarra,Sönke Szidat,M. N. Wehrli,Matthias Ruff,S. Weimer,S. Weimer,V. A. Lanz,Ernest Weingartner,N. Perron,Alexandre Caseiro,Alexandre Caseiro,Anne Kasper-Giebl,Hans Puxbaum,Lukas Wacker,Urs Baltensperger +16 more
TL;DR: In this article, a source apportionment method using the aethalometer light absorption parameters was applied to five winter campaigns at three sites in Switzerland: a village with high wood combustion activity in winter, an urban background site and a highway site.
