The IMPROVE_A Temperature Protocol for Thermal/Optical Carbon Analysis: Maintaining Consistency with a Long-Term Database
Judith C. Chow,John G. Watson,L.-W. Antony Chen,M.-C. Oliver Chang,Norman F. Robinson,Dana L. Trimble,Steven D. Kohl +6 more
TL;DR: A method to detect small quantities of O2 in the pure He carrier gas shows that O2 levels above 100 ppmv also affect the comparability of thermal carbon fractions but have little effect on the IMPROVE_TOR split between OC and EC.
Journal ArticleDOI
Source profiles for industrial, mobile, and area sources in the Big Bend Regional Aerosol Visibility and Observational study.
Judith C. Chow,John G. Watson,Hampden Kuhns,Vicken Etyemezian,Douglas H. Lowenthal,Dale Crow,Steven D. Kohl,Johann Engelbrecht,Mark C. Green +8 more
TL;DR: Abundances of eight thermally evolved carbon fractions differ among combustion sources, and a Monte Carlo simulation demonstrates that these differences are sufficient to differentiate among several carbon-emitters.
Journal ArticleDOI
Characterization of ambient PM2.5 at a pollution hotspot in New Delhi, India and inference of sources
TL;DR: In this paper, PM2.5 samples were collected at a high-traffic location (summer and winter 2013) and characterized for a large suite of elemental and organic markers.
Journal ArticleDOI
Molecular composition of organic fine particulate matter in Houston, TX
TL;DR: In this paper, the concentration of individual organic compounds in fine particulate matter collected in Houston, TX between March 1997 and March 1998 was analyzed to determine the concentrations of individual compounds, including molecular markers which are compounds unique to specific fine particle sources.
Journal ArticleDOI
Quality assurance and quality control for thermal/optical analysis of aerosol samples for organic and elemental carbon
Judith C. Chow,Judith C. Chow,John G. Watson,John G. Watson,Jerome Robles,Xiaoliang Wang,L.-W. Antony Chen,Dana L. Trimble,Steven D. Kohl,Richard J. Tropp,Kochy K. Fung +10 more
TL;DR: The quality assurance (QA) and quality control (QC) procedures that should be implemented to ensure consistency of OC and EC measurements are documented to aerosol sampling and analysis for carbon and other chemical components.
