TL;DR: A unifying model framework describing the atmospheric evolution of OA that is constrained by high–time-resolution measurements of its composition, volatility, and oxidation state is presented, which can serve as a basis for improving parameterizations in regional and global models.
Journal ArticleDOI
Chemical composition of fine aerosol measured by AMS at Fukue Island, Japan during APEX period
TL;DR: In this paper, the size distribution and chemical composition of ambient aerosols were analyzed using an Aerodyne aerosol mass spectrometer (AMS) at Fukue, Japan in the spring of 2003.
Journal ArticleDOI

TL;DR: Aerosol chemical composition and gaseous species were measured at Cape Hedo, Okinawa, Japan (CHO) during the ABC/EAREX project period in March 2005, using high-time-resolution instruments including an Aerodyne quadrupole aerosol mass spectrometer (Q-AMS), a tapered element oscillating microbalance (TEOM), and gas monitors in order to investigate the transport and subsequent chemical transformation of aerosol in the east Asian region as discussed by the authors.
Journal ArticleDOI
AMS and LC/MS analyses of SOA from the photooxidation of benzene and 1,3,5-trimethylbenzene in the presence of NO x : effects of chemical structure on SOA aging
Kei Sato,Akinori Takami,Y. Kato,T. Seta,Yuji Fujitani,Toshihide Hikida,Akio Shimono,Takashi Imamura +7 more
TL;DR: In this paper, the authors measured the mass spectra of secondary organic aerosol (SOA) formed from the photooxidation of aromatic hydrocarbons using an Aerodyne aerosol mass spectrometer (AMS) and reported that SOA aging is slowed with increasing number of alkyl groups in the precursor molecule.
Journal ArticleDOI
Mass spectrometric study of secondary organic aerosol formed from the photo-oxidation of aromatic hydrocarbons
TL;DR: In this article, the mass spectrum of secondary organic aerosol (SOA) formed from the photo-oxidation of aromatic hydrocarbons was studied by using Time-of-Flight AMS, and strong mass signals from SOA were found at m/z 43 (m43) and 44 (m44) in all the experiments.
