“…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).…”

“…The polarization of the outgoing radiance is notable. The polarization degree Q/I is considerably higher than typical values for thermal radiation of for example terrestrial atmospheric precipitation (Kutuza & Smirnov 1980;Kutuza et al 1998;Evtushenko et al 2002;Ilyushin & Kutuza 2016. This should be attributed to the polarizing properties of the refractive boundary which themselves are due to different transmission and reflection coefficients for s-and ppolarized radiation.…”

Context. We address the issue of remote sensing of the surfaces of Galilean icy moons. We investigate the prospects for retrieval of the physical parameters of the surface of the Jovian icy moons from submillimeter wave radiometry data. Aims. We show that the model parameters could not be completely retrieved from the polarized radiometry data, but some of their combinations can be effectively constrained. Methods. The polarized radiative transfer in lossy porous ice was numerically simulated. A Bayesian maximum likelihood retrieval algorithm was developed and tested on the simulated data in a wide range of variation of the model parameters. The uncertainty of the retrievals was evaluated with the Cramer-Rao bounds. We established the combinations of model parameters that can be effectively constrained from the measured data. Results. We reveal that the effective scatterer size can be reliably constrained for a range of values where the scattering asymmetry parameter uniquely depends on the wave parameter, and for relatively high values of the single scattering albedo, for which the scattering in the medium is significant. Similarly, the domains of reliable retrieval of the single scattering albedo and thermal skin depth are established.

“…In the present study, the three dimensional cubic rain cell model [14] is investigated and compared to the flat layered slab model of the raining atmosphere. Following to [12], we chose cubic rain cell model (3 × 3 × 3km ), uniformly filled with falling raindrops.…”

“…Boundary condition on the top surface of the rain cell is just zero boundary condition for the incoming radiation. Boundary conditions on side walls and bottom of the rain cell account for the thermal radiation coming from the heated underlying surface and lossy gray surrounding atmosphere [14].…”
