Polarimetric scattering model for methane bubbles trapped in the ice of sub-arctic lakes

In this work we propose a model for the polarimetric backscattering of shallow sub-arctic lakes, which are frozen usually up to two meters depth during winter. The model takes into account the inhomogeneities in the ice layer introduced mainly by CH
₄
bubbles trapped in the lake ice. The model is validated against experimental data acquired by ALOS-PalSAR.
