Abstract

We have investigated effects of the temperature dependence of water absorption indexes and of absorbing aerosols on the retrieval of cloud microphysical properties from the multi- spectral solar reflectance measurement by the airborne Multi- channel Cloud Pyranometer (MCP) system through collocated two- aircraft validation flights. For the clean liquid-water clouds, the reasonable cloud parameters were successfully retrieved by taking into account the temperature dependence of the complex refractive index of water by Kou et al. For the water cloud contaminated by absorbing aerosols, the present MCP-retrieval, under the assumption of pure liquid-water clouds, underestimated the visible optical thickness and overestimated the effective particle radius. The result suggests that new remote sensing techniques should be developed to discriminate and evaluate the effects of cloud particles and aerosols.
