Short summary

In our laboratory closure study, we measured the full set of aerosol optical properties for different light-absorbing aerosols using a set of instruments. Our key finding is that the extensive and intensive aerosol optical properties obtained agree with data from reference instruments, except the absorption Ångström exponent of externally mixed aerosols. The reported uncertainty in the single-scattering albedo fulfils the defined goals for Global Climate Observing System applications of 10 %.
