Short summary

This article presents a set of spectro-goniometric measurements of different water ice samples and their comparison with an approximated radiative transfer model using a Bayesian approach. Two kinds of experiments were conducted: the specular spot was investigated, and then the diffuse radiation. We show that the approximated model is able to reproduce the spectro-radiogoniometric data satisfactorily, and that the inverted parameters are compatible with independent measurements.
