Journal ArticleDOI
Primary emissions of glyoxal and methylglyoxal from laboratory measurements of open biomass burning
Kyle J. Zarzana,Kyle J. Zarzana,Kyle J. Zarzana,Vanessa Selimovic,Abigail R. Koss,Kanako Sekimoto,Kanako Sekimoto,Kanako Sekimoto,Matthew M. Coggon,Matthew M. Coggon,Bin Yuan,Bin Yuan,Bin Yuan,William P. Dubé,William P. Dubé,Robert J. Yokelson,Carsten Warneke,Carsten Warneke,Joost A. de Gouw,Joost A. de Gouw,Joost A. de Gouw,James M. Roberts,Steven S. Brown,Steven S. Brown +23 more
TL;DR: This article reported the emissions of glyoxal and methylglyoxal from open burning of biomass during the NOAA-led 2016 FIREX intensive at the Fire SciencesLaboratory in Missoula, MT.
Journal ArticleDOI
Heterogeneous chemistry involving methanol in tropospheric clouds
Azadeh Tabazadeh,Robert J. Yokelson,Hanwant B. Singh,Peter V. Hobbs,James H. Crawford,Laura T. Iraci +5 more
TL;DR: In this article, the authors analyze airborne measurements to suggest that methanol in biomass burning smoke is lost heterogeneously in clouds, and two plausible heterogeneous reactions are proposed to explain the observed simultaneous loss and production of methenol and formaldehyde, respectively.
Journal ArticleDOI
Inter-comparison of black carbon measurement methods for simulated open biomass burning emissions
Hanyang Li,Kara D. Lamb,Kara D. Lamb,Joshua P. Schwarz,Vanessa Selimovic,Robert J. Yokelson,Gavin R. McMeeking,Andrew A. May +7 more
TL;DR: In this article, principal component analysis combined with a K-means clustering algorithm was implemented to group different fires into three clusters based on several co-dependent fire-related parameters (modified combustion efficiency (MCE), single scattering albedo (SSA), organic carbon/elemental carbon ratio (OC/EC ratio), and absorption Angstrom exponents (AAE)), and clusters are nominally referred to as “Black, “Mixed, and “Brown” based on the mean SSA and AAE values for each.
Journal ArticleDOI
Rapidly evolving ultrafine and fine mode biomass smoke physical properties: Comparing laboratory and field results
Christian M. Carrico,Anthony J. Prenni,Sonia M. Kreidenweis,Ezra J. T. Levin,Christina S. McCluskey,Paul J. DeMott,Gavin R. McMeeking,Shunsuke Nakao,Chelsea E. Stockwell,Robert J. Yokelson +9 more
TL;DR: In this paper, the authors report sub-0.56 µm diameter (Dp) particle sizing with light absorption and scattering at 870 nm (photoacoustic extinctiometer).
Journal ArticleDOI
Isotopic characterization of nitrogen oxides (NO x ), nitrous acid (HONO), and nitrate ( p NO 3 − ) from laboratory biomass burning during FIREX
Jiajue Chai,David J. Miller,David J. Miller,Eric Scheuer,Jack E. Dibb,Vanessa Selimovic,Robert J. Yokelson,Kyle J. Zarzana,Kyle J. Zarzana,Kyle J. Zarzana,Steven S. Brown,Steven S. Brown,Abigail R. Koss,Carsten Warneke,Carsten Warneke,Meredith G. Hastings +15 more
TL;DR: In this paper, the isotopic composition of HONO from biomass burning (BB) emissions collected during the Fire Influence on Regional to Global Environments Experiment (FIREX, later evolved into FIRE-AQ) at the Missoula Fire Science Laboratory in the western US was verified using an annular denuder system.
