| Abstract | Introduction: Near-IR hyper-spectral imaging of clouds is currently used on Earth as a powerful meteorological tool, and this technique is made possible on Mars by the OMEGA (Observatoire pour la Minéralogie, l’Eau, les Glaces et l’Activité, [1]) imaging spectrometer. Past analyses of clouds have been done in the visible range with Mariner 9 and Viking Orbiter [2], and more recently in the visible (MOC images [3]) and thermal infrared (TES, 6 to 50 μm [4,5]) with Mars Global Surveyor. Bridging the gap, OMEGA data are spectral image cubes (x,λ,y) of the atmosphere and the surface both in the visible and near infrared, spanning 0.35 to 5.1 μm with a spectral sampling of 0.013-0.020 μm and kilometer-scale spatial resolution. Spectral range includes water ice absorption bands at 1.25, 1.5, 2 and 3 μm that can be used to detect water-ice clouds and derive their microphysical properties. Analyzing the kilometer-scale microphysics of clouds on Mars is key to understanding their formation, their role in the water cycle and radiative transfer of the planet, their interaction with the dust cycle, and can provide major insights into the fundamental physics of nucleation. |
