متن کاملEvidence that the spectral dependence of light absorption by aerosols is affected by organic carbon
[1] The wavelength dependence of light absorption by aerosols collected on filters is investigated throughout the near-ultraviolet to near-infrared spectral region. Measurements were made using an optical transmission method. Aerosols produced by biomass combustion, including wood and savanna burning, and by motor vehicles, including diesel trucks, are included in the analysis. These aerosol ty...
متن کاملBlack carbon or brown carbon? The nature of light-absorbing carbonaceous aerosols
Although the definition and measurement techniques for atmospheric “black carbon” (“BC”) or “elemental carbon” (“EC”) have long been subjects of scientific controversy, the recent discovery of light-absorbing carbon that is not black (“brown carbon, Cbrown”) makes it imperative to reassess and redefine the components that make up lightabsorbing carbonaceous matter (LAC) in the atmosphere. Evide...
متن کاملSpectral light absorption by ambient aerosols influenced by biomass burning in the Amazon Basin. I: Comparison and field calibration of absorption measurement techniques
Spectral aerosol light absorption is an important parameter for the assessment of the radiation budget of the atmosphere. Although on-line measurement techniques for aerosol light absorption, such as the Aethalometer and the Particle Soot Absorption Photometer (PSAP), have been available for two decades, they are limited in accuracy and spectral resolution because of the need to deposit the aer...
