| Abstract: | A computer method is described to calculate the light-scattering properties of randomly oriented, axially symmetric coated particles, in the framework of the T-matrix theory. Both the core and the shell can be axially symmetric nonspheroidal particles. Based on the coated spheroidal particle model, light scattering characteristics of water aerosols with an absorptive core (black carbon) are calculated. The effects of cores with different sizes and shapes are analyzed on extinction efficiencies, scattering efficiencies, absorption efficiencies, single scattering albedos, asymmetric parameters. |
