Veronika Pospisilova,David M. Bell,Houssni Lamkaddam,Amelie Bertrand,Liwei Wang,Deepika Bhattu,Deepika Bhattu,Xueqin Zhou,Josef Dommen,André S. H. Prévôt,Urs Baltensperger,Imad El Haddad,Jay G. Slowik +12 more
TL;DR: In this article, the chemical composition of α-pinene SOA exposed to UV-A light at 50% relative humidity in an atmospheric simulation chamber is characterized at a molecular level and in real time.
Journal ArticleDOI
Similarities in STXM-NEXAFS Spectra of Atmospheric Particles and Secondary Organic Aerosol Generated from Glyoxal, α-Pinene, Isoprene, 1,2,4-Trimethylbenzene, and d-Limonene
Kabindra M. Shakya,Shang Liu,Satoshi Takahama,Lynn M. Russell,Frank N. Keutsch,Melissa M. Galloway,John E. Shilling,Naruki Hiranuma,Chen Song,Hwajin Kim,Suzanne E. Paulson,L. Pfaffenberger,Peter Barmet,Jay G. Slowik,André S. H. Prévôt,Josef Dommen,Urs Baltensperger +16 more
TL;DR: In this paper, the organic functional group composition of particles produced in laboratory smog chambers were characterized by scanning transmission X-ray microscopy (STXM) with near-edge Xray absorption fine structure (NEXAFS) spectroscopy and characteristic spectral signatures for secondary organic aerosol (SOA) were identified.
Journal ArticleDOI
Towards on-line 14C analysis of carbonaceous aerosol fractions
N. Perron,Sönke Szidat,Simon Fahrni,Matthias Ruff,Lukas Wacker,André S. H. Prévôt,Urs Baltensperger +6 more
TL;DR: In this article, an on-line system that couples a commercial organic carbon (OC) analyzer with the gas ion source of the accelerator mass spectrometer (AMS) MICADAS and its CO2 feeding system is presented.

Source apportionment and the role of meteorological conditions in the assessment of air pollution exposure due to urban emissions
Klaus Schäfer,M. Elsasser,Jose M. Arteaga-Salas,Jianwei Gu,Mike Pitz,Jürgen Schnelle-Kreis,Josef Cyrys,Stefan Emeis,André S. H. Prévôt,Ralf Zimmermann +9 more
TL;DR: In this article, a case study of the urban atmosphere in the case of Augsburg, Germany, during winter (31 January-12 March 2010) is presented, where the results of the hierarchical clustering analysis with the Ward method of cross-correlations of each air pollutant and PM component and of the correlations of each pollutant with all meteorological parameters provided two clusters: "secondary pollutants of PM1 and fine particles" and "primary pollutants (including CO and benzene) and accumulation mode particles".
Posted ContentDOI
