Elevations from the Mars Orbiter Laser Altimeter (MOLA) have been used to construct a precise topographic map of the martian north polar region. The northern ice cap has a maximum elevation of 3 kilometers above its surroundings but lies within a 5-kilometer-deep hemispheric depression that is contiguous with the area into which most outflow channels emptied. Polar cap topography displays evidence of modification by ablation, flow, and wind and is consistent with a primarily H2O composition… Expand
Winter clouds over the North Martian Polar Cap
The Mars Orbiter Laser Altimeter (MOLA) experiment, carried on the Mars Global Surveyor spacecraft, has observed echoes from cloud tops on roughly 2.5% of the total data taken above 70°N over theExpand
Numerical simulation of the winter polar wave clouds observed by Mars Global Surveyor Mars Orbiter Laser Altimeter
Abstract In 1998, the Mars Orbiter Laser Altimeter revealed the presence of isolated or quasi-periodic thick clouds during the martian polar night. They are believed to be composed of CO 2 iceExpand

North polar stratigraphy and the paleo-erg of Mars
An accurate self-consistent way of coregistering the imaging and topographic data sets of the Mars Global Surveyor mission was developed and used to begin a stratigraphic analysis of the northernExpand
Martian North Polar Cap Recession: 2000 Mars Orbiter Camera Observations
Abstract The wide-angle cameras of the Mars Orbiter Camera (MOC) on the Mars Global Surveyor have recorded the 2000 recession of the seasonal CO 2 cap in the north polar region from L S =330° to 90°.Expand
The Role of Sublimation for the Formation of the Northern Ice Cap: Results from the Mars Orbiter Laser Altimeter
Abstract The evolutionary history of the martian ice caps is practically unknown, and the caps are key to understanding the climatic history of Mars. Sublimation and ice flow are two hypotheses thatExpand
