Collett,Teresa Campos,Brett B. Palm,Qiaoyun Peng,Joel A. Thornton,Lauren A. Garofalo,Delphine K. Farmer,Sonia M. Kreidenweis,Ezra J. T. Levin,Paul J. DeMott,Frank Flocke,Emily V. Fischer,Lu Hu +24 more
TL;DR: In this article, the authors present emissions measurements of volatile organic compounds (VOCs) for western U.S. 34 wildland fires made on the NSF/NCAR C-130 research aircraft during the Western Wildfire 35 Experiment for Cloud Chemistry, Aerosol Absorption, and Nitrogen (WE-CAN) field campaign.
Journal ArticleDOI
Quantitative IR spectrum and vibrational assignments for glycolaldehyde vapor: glycolaldehyde measurements in biomass burning plumes.
Timothy J. Johnson,Robert L. Sams,Luisa T. M. Profeta,S. K. Akagi,I. R. Burling,Robert J. Yokelson,Stephen D. Williams +6 more
TL;DR: The first assignment of all fundamental vibrational modes is completed and quantitative IR absorption band strengths are derived using both neat and pressure-broadened GA vapor, and the intensities agree well with the few previously published values.
Journal ArticleDOI
Photochemical Cloud Processing of Primary Wildfire Emissions as a Potential Source of Secondary Organic Aerosol
Sophie Tomaz,Tianqu Cui,Yuzhi Chen,Kenneth G. Sexton,James M. Roberts,Carsten Warneke,Carsten Warneke,Robert J. Yokelson,Jason D. Surratt,Barbara J. Turpin +9 more
TL;DR: In this paper, a high-resolution time-of-flight chemical ionization mass spectrometer using iodide reagent ion chemistry detected more than 100 gas-phase compounds from the emissions of 30 different controlled burns during the 2016 Fire Influence on Regional and Global Environments Experiment (FIREX) at the Fire Science Laboratory.
Journal ArticleDOI
Airborne characterization of smoke marker ratios from prescribed burning
Amy P. Sullivan,Andrew A. May,Taehyoung Lee,Gavin R. McMeeking,Sonia M. Kreidenweis,S. K. Akagi,Robert J. Yokelson,Shawn Urbanski,Jeffrey L. Collett +8 more
TL;DR: In this article, a Particle-Into-Liquid Sampler (PILS-TOC) and fraction collector system was flown aboard a Twin Otter aircraft sampling prescribed burning emissions in South Carolina in November 2011 to obtain smoke marker measurements.
Journal ArticleDOI
Ambient air quality in the Kathmandu Valley, Nepal, during the pre-monsoon: concentrations and sources of particulate matter and trace gases
Md. Robiul Islam,Thilina Jayarathne,Isobel J. Simpson,Benjamin Werden,John R. Maben,Ashley A. Gilbert,P. S. Praveen,Sagar Adhikari,Arnico K. Panday,Maheswar Rupakheti,Donald R. Blake,Robert J. Yokelson,Peter F. DeCarlo,Peter F. DeCarlo,William C. Keene,Elizabeth A. Stone +15 more
TL;DR: In this paper, the authors investigated the air quality in the Kathmandu valley during the pre-monsoon season 2015 and found that PM 2.5 concentrations ranged from 30 to 207 µ g'm −3, which exceeded the World Health Organization 24'hguideline by factors of 1.2 to 8.3.
