Interpreting Ganymede’s Microwave Emission: Modeling Emission and Scattering From Bright Terrain (opens in new tab)

An advanced microwave radiative transfer model is developed for Ganymede by enhancing the microwave emission model of layered snowpacks (MEMLS). It integrates topographic effects into the heat conduction equation for temperature profiles and treats ice as Rayleigh scatterers to address volume scattering. Channels 4–6 of Juno microwave radiometer (MWR) data, sensitive to the surface diurnal layer, are applied to investigate the microwave emission of bright terrains of Ganymede. Comparisons bet...
