Observations Of Water Frost On Mars With Themis Application To The Characterizing the exchange of water between the martian atmosphere and the (sub)surface is a major challenge for understanding the mechanisms that regulate the water cycle. here we present a new dataset of water ice detected on the martian surface with the thermal emission imaging system (themis). the detection is based on the correlation between bright blue white patterns in visible images. These data can also validate water frost predictions made by the mars planetary climate model [<]pcm,¿forget1999, lange2023model. this model, along with the processing of themis data, is presented in section 2. the results on water frost spatio temporal distribution, temperatures, and derived near surface water vapor are described in section 3.

Water ice observed with themis is most likely seasonal rather than diurnal. our dataset is consistent with near infrared spectroscopic data predictions by the mars planetary climate model. the water frost average temperature is 170 k, and the maximum temperature measured is 243 k, lower than the water ice melting point. Water ice observed with themis is most likely seasonal rather than diurnal. our dataset is consistent with near infrared spectroscopic data predictions by the mars planetary climate model. the water frost average temperature is 170 k, and the maximum temperature measured is 243 k, lower than the water ice melting point.

Frosted Crater Mars Odyssey Mission Themis Water ice observed with themis is most likely seasonal rather than diurnal. our dataset is consistent with near infrared spectroscopic data predictions by the mars planetary climate model. the water frost average temperature is 170 k, and the maximum temperature measured is 243 k, lower than the water ice melting point. Figure 1. spatial and seasonal distribution of themis visible thermal infrared pairs ana "observations of water frost on mars with themis: application to the presence of brines and the stability of (sub)surface water ice". Section snippets seasonal water ice in the north polar region. the north pole of mars is covered by a residual ice cap that is believed to be composed primarily of water ice, due to observations of the column abundance of water vapor and thermal emission measurements of the cap temperature (kieffer et al., 1976, jakosky, 1985). The evidence from both themis and tes observations of korolev crater show distinct regions within the crater, largely due to variations in elevation and location. tes observations reveal that in late summer, high albedo deposits form within the crater when the temperature exceeds the co 2 frost point. thermal modeling of the subsurface suggests.
