Short summary

The study used a photoacoustic spectrometer as a reference instrument to determine the multiple-scattering correction factor C_λ for an AE33 aethalometer at three wavelengths, which we believe is critical for aerosol absorption measurements using aethalometer. This is an important parametrization of C_λ specifically geared towards BB aerosol from African fuels under different aging states, and is of particular importance for future field work in that continent which is at present least studied.
