Strong spectral variation of biomass smoke light absorption and single scattering albedo observed with a novel dual-wavelength photoacoustic instrument (2008, methodology): “Aethalometers have been found to over predict BC concentration on a fresh filter and under predict it on a loaded filter [Arnott et al., 2005].”
Deriving brown carbon from multiwavelength absorption measurements: method and application to AERONET and Aethalometer observations (2016, background): “It is commonly thought that the absorption measurements from Aethalometers are biased towards much higher values (Arnott et al., 2005; Schmid et al., 2006).”
