Short summary
An evaluation of the performance and accuracy of a Cavity Attenuated Phase-Shift Single Scattering Albedo Monitor (CAPS PMSSA; Aerodyne Research, Inc.) was conducted in an optical-closure study with proven technologies for aerosol particle optical-property measurements. This study demonstrates that the CAPS PMSSA is a robust and reliable instrument for the direct measurement of the particle scattering and extinction coefficients and thus single-scattering albedo.
