We propose a conceptual model to interpret AM/PM high albedo events (HAEs) in crater interiors at the Martian seasonal polar caps. This model consists of two components: (1) a relatively permanent high-albedo water–ice body exposed in a crater interior and (2) a variable crater albedo in response to aerosol optical depth, dust contamination, and H2O/CO2 frost deposits or sublimes in four phases, based on temperature and solar longitude changes. Two craters (Korolev crater of fully exposed water… Expand

Survey of TES high albedo events in Mars' northern polar craters
[1] Following the work exploring Korolev Crater (Armstrong et al., 2005) for evidence of crater interior ice deposits, we have conducted a survey of Thermal Emission Spectroscopy (TES) temperatureExpand
Evidence for subsurface water ice in Korolev crater, Mars
Abstract Following the work of Kieffer and Titus (2001, Icarus 154, 162–180), we present results of thermal IR observations of Korolev crater, located at ∼ 73 ° latitude in the martian northern polarExpand
Variability of Mars' North Polar Water Ice Cap: II. Analysis of Viking IRTM and MAWD Data
Abstract We have examined Viking Orbiter albedo, thermal, and atmospheric water vapor data acquired during Mars' northern summer season and compared these results with the imaging results of D. S.Expand
Isolated Water Ice in an Unnamed Crater Away from the Residual North Polar Cap of Mars: The Only One?
Introduction: The Martian poles are covered by large quantities of water ice. The water ice in the north polar region is partially covered by CO2 ice during the Martian winter and spring, andExpand
North Polar Region Craterforms on Mars: Geometric Characteristics from the Mars Orbiter Laser Altimeter
Abstract This study focuses on topographic characterization of ice-associated north polar region impact craters and several enigmatic polar craterforms using new information from the Mars OrbiterExpand
Martian climatic events on timescales of centuries: Evidence from feature morphology in the residual south polar ice cap
Flat-floored, quasi-circular depressions on the southern residual cap of Mars have been observed to expand rapidly. Analysis of the size distribution combined with modeling of the growth processExpand
Perennial water ice identified in the south polar cap of Mars
This work presents the first direct identification and mapping of both carbon dioxide and water ice in the martian high southern latitudes, at a resolution of 2 km, during the local summer, when the extent of the polar ice is at its minimum. Expand
Monitoring the perennial martian northern polar cap with MGS MOC
Abstract We have used the Mars Global Surveyor Mars Orbiter Camera Wide Angle (MGS MOC WA) dataset to study albedo trends on the martian northern residual cap. Six study regions were selected, theExpand
The Martian annual atmospheric pressure cycle: Years without great dust storms
A model of the annual cycle of pressure on Mars has been developed for a 2-year period chosen to include 1 year at Lander 2 and to minimize the effect of great dust storms at the 22°N Lander 1 site.Expand
Summer Evolution of the North Polar Cap of Mars as Observed by OMEGA/Mars Express
The Observatoire pour la Mine, l'Eau, les Glaces, et l'Activite (OMEGA) visible-infrared imaging spectrometer extensively observed regions of Mars with latitudes above 70°N in late 2004 and the extent of water ice at the surface and the size of ice grains were monitored as a function of time. Expand
