The depth to which solar radiation can penetrate through ice is an important factor in understanding surface‐atmosphere interactions for icy planetary surfaces. Mars hosts both water and carbon dioxide ice on the surface and in the subsurface. At high latitudes during autumn and winter carbon dioxide condenses to form the seasonal polar cap. This has been both modeled and observed to, in part, occur as snowfall. As snow accumulates, the thermal properties of the surface are changed, whether the… 
The Penetration of Solar Radiation Into Granular Carbon Dioxide and Water Ices of Varying Grain Sizes on Mars
The penetration depth of broad spectrum solar irradiation over the wavelength range 300–1,100 nm has been experimentally measured for water and carbon dioxide ices of different grain size ranges.
Growth of carbon dioxide whiskers
We report the growth of carbon dioxide (CO2) whiskers at low temperatures (−70 °C to −65 °C) and moderate pressure (4.4 to 1.0 bar). Their axial growth was assessed by optical video analysis. The


The Penetration of Solar Radiation Into Carbon Dioxide Ice
Icy surfaces behave differently to rocky or regolith‐covered surfaces in response to irradiation. A key factor is the ability of visible light to penetrate partially into the subsurface. This results
Penetration of solar radiation into pure and Mars-dust contaminated snow
Carbon dioxide ice clouds, snowfalls, and baroclinic waves in the northern winter polar atmosphere of Mars
The formation of CO2 ice clouds in the northern winter polar atmosphere of Mars and their relation to baroclinic planetary waves, which dominate local dynamics, are studied using a general
Temporary liquid water in upper snow/ice sub-surfaces on Mars?
Carbon dioxide snow clouds on Mars: South polar winter observations by the Mars Climate Sounder
[1] We present south polar winter infrared observations from the Mars Climate Sounder (MCS) and test three hypotheses concerning the origins of “cold spots”: regions of anomalously low infrared
Annual Punctuated CO 2 Slab-Ice and Jets on Mars
Thermal Emission Spectrometer (TES) observations indicate that some areas of Mars' seasonal south cap, informally called the "Cryptic" region, are composed of CO2 ice of indeterminately large grain
Behavior of Carbon Dioxide and Other Volatiles on Mars
We have found that a rather simple thermal model of the Martian surface, in combination with current observations of the atmospheric composition, points strongly toward the conclusion that the polar
Seasonal Variations of Snow Depth on Mars
Using topography collected from the Mars Orbiter Laser Altimeter on the MGS spacecraft, temporal changes in the elevation of the martian surface that correlate with the seasonal cycle of carbon dioxide exchange between the surface and atmosphere are measured.
