Vertical distribution of water at Phoenix
Phoenix results, combined with coordinated observations from the Mars Reconnaissance Orbiter of the Phoenix lander site, indicate that the water vapor is nonuniform (i.e., not well mixed) up to a calculated cloud condensation level [1]. It is important to understand the mixing profile of water vapor...
