A mapping of martian water sublimation during early northern summer using OMEGA/Mars Express

Bibring, J. -P.; Gondet, B.; Langevin, Y. +8 more

The OMEGA imaging spectrometer aboard Mars Express has been used to map the water vapor abundance over the martian surface, from the analysis of the 2.6 µm band of H2O. As a preliminary result of this study, we present water vapor maps in the northern hemisphere at the time of the northern polar cap sublimation (Ls = 94-112 deg). The maps sh…
