Aerosol light absorption and its measurement: A review (2009, background): “74, respectively, good agreement between the extinction-minus-scattering technique and photoacoustic [55] and MAAP [40,41] measurements was found [348].”
Relative humidity dependence of aerosol optical properties and direct radiative forcing in the surface boundary layer at Xinken in Pearl River Delta of China : An observation based numerical study (2008, background): “Multi-angle absorption photometry (MAAP, Thermo 5012, attenuation cross section of 6:6m(2) g (1)) (Petzold and Kramer, 2001; Petzold and Schönlinner, 2004; Petzold et al., 2005).”
Mass Absorption Cross-Section of Ambient Black Carbon Aerosol in Relation to Chemical Age (2009, background): “Light scattering can also be the result of interactions between aerosols and filters and these interactions, not being solely attributable to the properties of aerosols themselves, introduce measurement artefacts ( Petzold and Schonlinner 2004 ; Petzold et al.”
The Reno Aerosol Optics Study: An Evaluation of Aerosol Absorption Measurement Methods (2005, methodology): “A third type of filter-based lightabsorption instrument, called multiangle absorption photometer (MAAP; ThermoESM/Anderson), was also compared in this study (Petzold and Schönlinner 2004).”
Size-resolved measurements of brown carbon in water and methanol extracts and estimates of their contribution to ambient fine-particle light absorption (2013, background): “MAAP b ap uncertainty is estimated at 12 % (Petzold and Schönlinner, 2004).”
Towards Aerosol Light-Absorption Measurements with a 7-Wavelength Aethalometer: Evaluation with a Photoacoustic Instrument and 3-Wavelength Nephelometer (2005, methodology): “…transmittance and reflectance at a wavelength of 670 nm, couple these measurements with a multiple scattering model, and thus produce a robust measure of aerosol light absorption from measurements all obtained with this single instrument (Petzold et al. 2002, 2005; Petzold and Schönlinner 2004).”
Evaluation of Multiangle Absorption Photometry for Measuring Aerosol Light Absorption (2005, methodology): “The solution of the equation of radiative transfer (Hänel 1987; Petzold and Schönlinner 2004) yields equations for the quantities FL, BL, P∗ L , and B ∗ L as functions of the ratio of light scattering to light extinction by the aerosol-loaded filter, which is the single-scattering albedo of the aero”
