The Sentinels missions represent a major opportunity for advancing science in terms of innovative methods, novel products and new Earth system science results. The massive amount of data provided by Sentinels 1, 2 and 3 A and B units together with additional observations (satellite and in-situ) and models over land areas is opening the door to unprecedented capacity to monitor and characterise land processes and its interactions from global to local scales. This session aims at reviewing the latest advancements in science made possible by the Sentinel series over land and exploring the potential future applications that science results may bring in the next future.
