Time-averaged absorption, babs (a), and scattering, bsca (b), coefficients along with the respective mass absorption cross-section, MAC (c), and single scattering albedo, SSA (d), measured on June 7 (red filled bars), 8 (green lined bars) and 12 (blue dotted bars). The error bars quantify the variation of the WFPM optical properties during the measurement campaign. The standard deviations of the MAC and SSA were calculated based on those of the measured babs and bsca. The MAC and SSA measured on June 7 are compared to those derived by Mie theory based on the measured mobility size distribution and EC/OC content (yellow open bars). The transport time of WFPM on June 7 and 8 was about 24 and 36 h, respectively. Error bars show the standard deviation of babs, bsca, MAC and SSA during the sampling period.
