The Phoenix Mars lidar was successfully operated through 90 sols of the primary mission, and provide both spatial and temporal data on the distribution of Aeolian scatterers in the Martian atmosphere. Measurements were obtained at a variety of times throughout the diurnal cycle, and show a pattern early in the mission of enhanced scattering signal at the top of the dust boundary layer during the afternoon. Similar features were observed in November of 2007 in the Australian desert with an analogous lidar system, and simultaneous in situ aircraft measurements indicate that such signal enhancements correlate with periods of increased relative humidity. The vertical water content distribution in the Martian atmosphere during such events was thus considered in the context of lidar scattering signals, and a comparison of both Martian and Terrestrial results will be presented.
