Abstract

For optical satellite remote sensing of the marine arctic environment it is essential to establish appropriate knowledge of its optical properties. To that end we used a multi stream radiative transfer (RT) code to study the penetration of spectral irradiances in a coupled atmosphere-ice-ocean system. The code account for the change in the refractive index at the atmosphere-ice interface. To validate and tune this coupled RT model we ran the code with input from in situ measurements of optical properties and compared the computed results with in situ spectral irradiance measurements. The field work was done in Kongsfjorden, Svalbard, and the measurements were performed for first year ice. One goal of this study was to establish a model for the optical properties of the marine arctic environment that can be used in the interpretation of satellite remote sensing data.
