Resumo: Aerosol light absorption is an important parameter for the assessment of the radiation budget of the atmosphere. Filter based absorption photometers, e.g. the Aethalometer and the Particle Soot Absorption Photometer (PSAP) have been available for several years. Multiple scattering of light in the filter medium and the presence of scattering particles result in a measured attenuation coefficient, which is different from the absorption coefficient of airborne particles. Correction schemes have to be determined experimentally using reference methods (e.g. photoacoustic photometers or extinction minus scattering). Often used correction schemes are described in Bond et al. (1999) and Virkkula et al. (2005) for PSAP and in Weingaartner et al. (2003) for Aethalometer. In the frameworks of EUSAAR a workshop for testing existing and developing new correction schemes has been conducted in 2009 at the Leibniz Institute for Tropospheric Research in Leipzig.
