Impact of updated radiative properties of dust in the GCM

Report on the impact of updated radiative properties of dust in the GCM effects on temperature and general circulation patterns The GCM requires particles shape through the aspect ratio crosssection refractive index single scattering albedo extinction efficiency and asymmetry factors for dust and water ice particles to compute its radiative effects in the atmosphere These values will be updated for dust using results obtained from Task 26 New simulations will be performed and an evaluation of the impacts will be reported In addition the impact of including polarization in the radiative transfer calculations will be investigated
