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
Equivalence of elemental carbon by thermal/optical reflectance and transmittance with different temperature protocols.
Judith C. Chow,John G. Watson,L.-W. Antony Chen,W. Patrick Arnott,Hans Moosmüller,Kochy Fung +5 more
TL;DR: This work demonstrates that thermal/ optical reflectance (TOR) corrections yield equivalent OC/ EC splits for widely divergent temperature protocols, and results determined by simultaneous thermal/optical transmittance (TOT) corrections are 30% lower than TOR for the same temperature protocol and 70-80% lower for a protocol with higher heating temperatures and shorter residence times.
Journal ArticleDOI
Summary of Organic and Elemental Carbon/Black Carbon Analysis Methods and Intercomparisons
TL;DR: Many different thermal, optical, and thermal/optical carbon analysis methods for organic carbon (OC), elemental carbon (EC) or black carbon (BC) have been applied throughout the world to evaluate visibility and the Earth's radiation balance as mentioned in this paper.
Journal ArticleDOI

TL;DR: Important factors for improving agreement between measured and reconstructed PM mass are the f multiplier for converting OC to OM and accounting for OC sampling artifacts.
Journal ArticleDOI
Source Apportionment: Findings from the U.S. Supersites Program
TL;DR: UNMIX, positive matrix factorization (PMF), and effective variance are different solutions to the chemical mass balance (CMB) receptor model equations and are implemented on available software.
