Short summary

Black carbon measurements are usually conducted with absorption filter photometers, which are prone to the filter-loading effect – a saturation of the instrumental response due to the accumulation of the sample in the filter matrix. In this paper, we conducted several field campaigns to investigate the hypothesis that this filter-loading effect depends on the optical properties of particles present in the filter matrix, especially on the coating of black carbon particles.
