Using Cavity Attenuated Phase Shift-based Instruments to Measure NO2 and Aerosol Optical Properties

CAPS, aerosol extinction, single scattering albedo, nitrogen dioxide

Measurements of ambient nitrogen dioxide and aerosol optical properties including single scattering albedo using instrumentation based on cavity attenuated phase shift techniques are readily made. A description of the instruments and their applications to measurement of ambient atmospheric species will be presented. Aside from ambient monitoring, examples include measurement of: NO2 vertical profiles up to 6000 m altitude, soot emissions from jet aircraft engines and aerosol single scattering albedo in an isolated marine environment.
