El-Maarry, Space And Planetary Science Center, And Department Of Earth Sciences, Khalifa University, Abu Dhabi, Uae Introduction: A Considerable Record Of Martian Water Ice Cloud Observations Has Now Been Produced From The Combined Measurements Of Numerous Mars Missions. However, Much Of This Record Is Derived From Sun-Synchronous Spacecraft That Observe At Roughly The Same Local Time Across Their Domain (Typically Early Afternoon) Or Surface Instruments With No Spatial Coverage Beyond The Lander Location. Where Local Time Variable Observations Of Water Ice Cloud Exist, Spatial, Temporal, Or Seasonal Coverage Is Often Limited. Such Bounds To Observational Coverage
