Characterizing the exchange of water between the Martian atmosphere and the (sub)surfaceis a major challenge for understanding the mechanisms that regulate the water cycle. Herewe present a new dataset of water ice detected on the Martian surface with the Ther-mal Emission Imaging System (THEMIS). T...
