Atmospheric light absorption : a review
598
TL;DR: In this paper, the authors used a variety of refractive indices to measure the light absorption coefficient of suspended particles in the atmosphere and found that the mass extinction coefficient of soot is higher by a factor of two to three compared to transparent particles.

Sources of fine particle composition in the northeastern US
TL;DR: In this paper, the authors used positive matrix factorization (PMF) to extract sources from the ambient aerosol concentration data at three sampling sites in the northeastern US using a relatively new type of factor analysis.
Measuring the Mass Extinction Efficiency of Elemental Carbon in Rural Aerosol
TL;DR: In this paper, the mass extinction efficiency (m 2 g -1 ) of ambient elemental carbon (EC) is measured as a function of particle size and wavelength of light, where the filter samples are extracted in a mixture of 30% isopropanol and 70% deionized distilled water to form a suspension of insoluble EC particles.

TL;DR: In this article, an internal consistency algorithm was developed to model the mass ratio (r) of externally mixed elemental carbon (EC) to total EC, which minimized the discrepancies between measured and calculated optical properties.
Influence of fuel sulfur on the characterization of PM10 from a diesel engine
TL;DR: In this paper, the effects of fuel sulfur content on the characteristics of diesel particle emitted from a typical engine used in China, two types of diesel fuel with sulfur content of 30 and 500 parts per million (ppm) were used in this engine dynamometer test under six operation conditions corresponding to 20, 50% and 80% load at 1400 and 2300rpm engine speeds, respectively.
Development of an improved optical transmission technique for black carbon (BC) analysis
TL;DR: In this article, a new optical transmission technique for black carbon (BC) analysis was developed to minimize interferences due to scattering effects in filter samples, which is often done for microscopy purposes.
