Journal ArticleDOI
A 1-year characterization of organic aerosol composition and sources using an extractive electrospray ionization time-of-flight mass spectrometer (EESI-TOF)
Lu Qi,Lu Qi,Alexander L. Vogel,Sepideh Esmaeilirad,Li-Ming Cao,Jing Zheng,Jean-Luc Jaffrezo,Paola Fermo,Anne Kasper-Giebl,Kaspar R. Daellenbach,Kaspar R. Daellenbach,Mindong Chen,Xinlei Ge,Urs Baltensperger,André S. H. Prévôt,Jay G. Slowik +15 more
TL;DR: In this article, the authors applied positive matrix factorization (PMF) to EESI-TOF spectra to identify key factor-specific ions based on PMF.
Journal ArticleDOI

Neeraj Rastogi,Rangu Satish,Atinderpal Singh,Varun Kumar,Navaneeth M. Thamban,Vipul Lalchandani,Ashutosh Shukla,Pawan Vats,Sachchida Nand Tripathi,Dilip Ganguly,Jay G. Slowik,André S. H. Prévôt +11 more
TL;DR: In this paper, the spectral properties of water-soluble BrC (hereafter BrC) were measured using an assembled system including a particle-into-liquid sampler, portable UV-Visible spectrophotometer with liquid waveguid capillary cell, and total carbon analyzer (PILS-LWCC-TOC).
Journal ArticleDOI
Simultaneous retrieval of aerosol and surface optical properties using data of the Multi-angle Imaging SpectroRadiometer (MISR)
TL;DR: In this article, an algorithm for retrieving simultaneously aerosol and surface optical properties from radiance data of the Multi-angle Imaging SpectroRadiometer (MISR) was developed.
Journal ArticleDOI
Cooking and electronic cigarettes leading to large differences between indoor and outdoor particle composition and concentration measured by aerosol mass spectrometry
Yuliya Omelekhina,Axel Eriksson,Francesco Canonaco,André S. H. Prévôt,Patrik Nilsson,Christina Isaxon,Joakim Pagels,Aneta Wierzbicka +7 more
TL;DR: The chemical composition and concentration of particles indoors showed large differences compared to outdoors, and four factors were identified in the source apportionment of organic particle fraction by applying positive matrix factorization (PMF).
Journal ArticleDOI
Photochemical modelling in the Po basin with focus on formaldehyde and ozone
L. Liu,L. Liu,F. Flatoy,Carlos Ordóñez,Geir O. Braathen,C. Hak,Wolfgang Junkermann,S. Andreani-Aksoyoglu,Johan Mellqvist,Bo Galle,André S. H. Prévôt,Ivar S. A. Isaksen +11 more
TL;DR: In this article, a 3D regional chemical transport model (NILU RCTM) was used to interpret the observations focusing primarily on HCHO and ozone, and the performance of the model was assessed by comparing model results with ground-based and aircraft measurements.
