Antarctica is an immense continent made of ice. This region remains to this day one of the most unknown regions of our planet Earth. It contains nearly 90% of the world's fresh water, and in the current situation of global warming, this frozen reservoir is under serious threat. In the absence of reliable observations or efficient climate models, it is so far difficult to verify what is happening in Antarctica, and how it may evolve in the coming decades. Indeed, some studies predict significant ice melt in the west, other studies predict snow accumulation at the surface of its eastern region, mostly by precipitation events. It is, however, difficult to know if one of these two processes takes priority over the other, and which one.The Cloud...
