Abstract

A radiative transfer model designed for sea ice with vertical layering is presented which removes several of the computational problems associated with translucent media whose optical properties are strong functions of wavelength. Accurate results are achieved for both direct and diffuse incident irradiance for single scattering co-albedos ranging from 1.0 to l08. Calculated snow and sea ice albedos and extinction coefficients are consistent with both observations and previous models, and resolve certain apparent inconsistencies in previous observational results. Algae absorption has a significant effect on transmitted radiation but seems to be quite variable. Transmitted irradiances vary by more than a factor of 3 at certain visible wavelengths.
