Polarimetry is a powerful diagnostic tool providing a wealth of information about objects from the Earth atmosphere to the far universe that cannot be obtained by traditional photometric/spectroscopic observations. In the solar system polarimetry has been widely used e.g. to characterize the surface of atmosphereless bodies, dust and aerosols in planetary atmospheres, in cometary environments and in the interplanetary dust cloud, or to explore the magnetism of the solar atmosphere. In the case of Earth's atmosphere, polarimetry has many applications including aerosols and dust characterization, study of the formation of auroral emission lines. This session is open to papers about recent polarimetric observations of solar system bodies including the Earth and the Sun, theoretical or experimental investigations and instrumental developments for polarimeters to be included in ground-based facilities or onboard future space missions. Contributions about detection and/or characterization of exoplanets with polarimetry are very welcome.
