TLDR
In this article, the attenuation attenuation (ATN) of visible light as it passes through filter samples was measured for a large number of solvent-extracted source and ambient particle samples using temperature-programmed evolved gas analysis with continuous light attenuation measurement.About:

TL;DR: In this paper, the authors provided an assessment of black-carbon climate forcing that is comprehensive in its inclusion of all known and relevant processes and that is quantitative in providing best estimates and uncertainties of the main forcing terms: direct solar absorption; influence on liquid, mixed phase, and ice clouds; and deposition on snow and ice.

Light Absorption by Carbonaceous Particles: An Investigative Review
Tami C. Bond,Robert Bergström +1 more
TL;DR: The optical properties of light-absorbing, carbonaceous substance often called "soot", "black carbon", or "carbon black" have been the subject of some debate as discussed by the authors.

TL;DR: This article presented a bottom-up estimate of uncertainties in source strength by combining uncertainties in particulate matter emission factors, emission characterization, and fuel use, with uncertainty ranges of 4.3-22 Tg/yr for BC and 17-77 Tg /yr for OC.

Black carbon or brown carbon? The nature of light-absorbing carbonaceous aerosols
TL;DR: In this article, the authors show that brown carbon may severely bias measurements of atmospheric "black carbon" and "elemental carbon" over vast parts of the troposphere, especially those strongly polluted by biomass burning, where the mass concentration of C brown is high relative to that of soot carbon.
Journal ArticleDOI
Evidence that the spectral dependence of light absorption by aerosols is affected by organic carbon
TL;DR: In this paper, the wavelength dependence of light absorption by aerosols collected on filters is investigated throughout the near-ultraviolet to near-infrared spectral region using an optical transmission method.

Identification of the optically absorbing component in urban aerosols
TL;DR: Raman spectroscopy is used to determine the absorptivity of urban particulates for combustion sources and its application in combustion sources is still under investigation.

Analysis of carbonaceous materials in Southern California atmospheric aerosols
TL;DR: In this article, a technique for estimating the contributions of elemental carbon and primary organic and secondary organic materials to atmospheric particulate matter collected in California's South Coast Air Basin is described.
Journal ArticleDOI
Photoacoustic investigation of urban aerosol particles
TL;DR: A photoacoustic investigation gives an independent verification of the hypothesis that the absorbing species in urban par ticulates is graphitic carbon and questions have been raised whether the optical attenuation technique exclusively mea sures the absorbing rather than the scattering component of the aerosol.
