Absorption of light by soot particles: determination of the absorption coefficient by means of aethalometers
TLDR
In this article, the response of two different aethalometers (AE10 with white light and AE30 with multi-wavelength capability) to several types of soot was investigated, including diesel soot, spark-generated carbon particles, and mixtures of these soot particles with ammonium sulfate and oxidation products of �pinene.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.

The aethalometer — An instrument for the real-time measurement of optical absorption by aerosol particles
TL;DR: In this article, the authors describe an instrument that measures the concentration of optically absorbing aerosol particles in real time, which is normally due to black carbon, a good tracer for combustion emission.

Calibration and Intercomparison of Filter-Based Measurements of Visible Light Absorption by Aerosols
TL;DR: In this paper, a calibration of a recently developed filter-based instrument for continuous measurement of light absorption (model PSAP, Radiance Research, Seattle, WA) that has been incorporated in several measurement programs is presented.

TL;DR: The microphysical properties of Diesel and spark generator soot were investigated in detail during the AIDA Soot Aerosol Campaign 1999 as discussed by the authors, and the mass specific extinction cross section at λ=450 nm of Diesel soot is 106±05 m 2 g −1 which is almost a factor of two larger than the corresponding value of 57±03 m 2g −1 measured for spark generator SOOT.

Optical and thermal measurements of black carbon aerosol content in different environments: Variation of the specific attenuation cross-section, sigma (σ)
TL;DR: In this article, the specific attenuation cross-section of a light beam due to the absorption of aerosols deposited on a filter into their black carbon content was investigated using both optical analysis (with an aethalometer) and thermal analysis of black carbon aerosols.
