摘要
The LIDAR instrument on the Phoenix mission provided observations of clouds within the Planetary Boundary Layer (PBL) on Mars. In mid to late summer there was a regular Sol-to-Sol pattern with cloud formation at around midnight and dissipation before midday. The ice water content (IWC) of the clouds was estimated from the measurements with peak values at 6 am of 1 mg/m(3), associated with total column IWC of up to 5 g/m(2). The time of cloud formation did not change throughout the second half of the mission. This is consistent with the expected atmospheric cooling, if the observed decreasing trend in the column amount of water occurred mainly within the PBL. Citation: Dickinson, C., J. A. Whiteway, L.
