Inferring black carbon content and specific absorption from Aerosol Robotic Network (AERONET) aerosol retrievals (2005, background): “Arnott et al. [2003] measured 8.1 m 2 g � 1 during the summer and fall at the Big Bend”
Amplification of Light Absorption of Black Carbon by Organic Coating (2010, methodology): “Therefore, the absorption measurement of coated BC particles by PASS might be influenced by evaporation of volatile components of the coated BC (Arnott et al. 2003).”
Aerosol Absorption Measurement using Photoacoustic Spectroscopy: Sensitivity, Calibration, and Uncertainty Developments (2006, methodology): “Arnott et al. (2003) and Raspet et al. (2003) investigated this phenomenon for ambient and theoretical aerosols, respectively, and suggest that aerosol be dried below 65–70% RH to avoid evaporation biases.”
Aerosol light absorption and its measurement: A review (2009, methodology): “A quantitative treatment of this effect can follow the photoacoustic treatment [273,300,301] but also needs to consider the change of refractive index due to the mixing of the evaporated semi-volatile material with the surrounding air.”
Towards Aerosol Light-Absorption Measurements with a 7-Wavelength Aethalometer: Evaluation with a Photoacoustic Instrument and 3-Wavelength Nephelometer (2005, background): “Some fraction of aerosol scattering gives rise to a nonzero B aeth , even though B abs ≈ 0, as expected, and as measured with the photoacoustic instrument ( Moosmuller et al. 1998 ; Arnott et al.”
Evaluation of Multiangle Absorption Photometry for Measuring Aerosol Light Absorption (2005, methodology): “The offset of MAAP data compared to photoacoustic data as found in the laboratory aerosol data occurs consistently in the ambient aerosol data and may be connected to photoacousticspecific reasons (see also Arnott et al. 2003).”
Correction of the Calibration of the 3-wavelength Particle Soot Absorption Photometer (3λ PSAP) (2010, background): “In these experiments there were neither any condensing material, such as organics nor high or variable relative humidities that have been shown to disturb filter-based absorption measurements (eg, Arnott et al. 2003 ; Cappa et al.”
A study of radiative properties of fractal soot aggregates using the superposition T-matrix method (2008, methodology): “Our results are also important for optical diagnostics of combustion-generated soot aggregates as well as atmospheric measurements of light absorption using the photoacoustic method [25,26].”
