An instrument, carried on the International Space Station, has captured the recent land-surface temperature extremes for some European cities, including Milan, Paris and Prague. For ESA, this particular instrument, which is called ECOSTRESS and owned by NASA's Jet Propulsion Laboratory (JPL), is important because it is helping in the development of a new Copernicus Sentinel satellite: the Land Surface Temperature Monitoring (LSTM) mission. ESA is using the instrument to simulate the data that will eventually be returned by LSTM, which will provide systematic measurements of the temperature of the land surface, promising to be a game-changer for urban planners and farmers, for example.
