“…Radiative transfer models have been proposed to simulate the effects of scattering within both atmospheres (e.g., Kokhanovsky et al, 2010;Ilyushin and Kutuza, 2016) and solid surfaces (e.g., Kuga et al, 1991;Wiesmann and Mätzler, 1999;Mishchenko et al, 1999;Moroz, 2005;Liang et al, 2008;Ulaby and Long, 2015) on the outgoing radiation. Nonetheless, in order to limit both the complexity of the model and the number of parameters we have made the choice of a scatter-free radiative transfer model, like Le Gall et al (2014) (see also Keihm et al, 2013 for asteroids).…”
