Short summary

An instrument-dependent wavelength-independent parameter (C) is often used to face multiple-scattering issues affecting aerosol light absorption measurements by Aethalometers. Instead, we determined multi-wavelength C by comparison with absorption measurements of samples collected in parallel performed by an instrument developed in-house. Considering C wavelength dependence, harmonized results were obtained applying source and component apportionment models to data from different Aethalometers.
