英文摘要 | The spectral dependence of aerosol light absorption (alpha(abs)) and single-scattering albedo-[omega, defined as the ratio of the scattering (alpha(scat)) and extinction coefficients (alpha(ext) = alpha(abs) + alpha(scat))]-has proven effective in classifying dominant aerosol types. It is also helpful in understanding aerosol sources, transformation, climate and environmental effects, testing aerosol models. and improving the retrieval accuracy of satellite and remote sensing data. Despite the significant progress that has been made with measurement of light absorption and omega, many of the reported instruments either operate at a fixed wavelength or can only measure a single optical parameter. Quantitative multi-parameter wavelength-dependent measurement re mains a challenge. In this work. a three-wavelength cavity-enhanced albedometer was developed. The albedometer can measure multiple optical parameters, alpha(ext), alpha(scat), alpha(abs) and omega, at lambda = 365, 532, and 660 nm, in real time. The instrument's performance was evaluated using four different type laboratory generated aerosols, including polystyrene latex spheres (PSL, non-absorbing); ammonium sulfate (AS, non-absorbing); suwannee river fulvic acid (SRFA, slightly absorbing; a proxy for light absorbing organic aerosol); and nigrosin (strongly absorbing).
