Satellite-based Earth observation is the only technology that allows us to monitor the atmosphere and climate worldwide around the clock. Satellites continuously and reliably collect large amounts of data, for example on concentrations of greenhouse and trace gases, cloud cover, and ocean and land surface temperatures. Reliable weather forecasts and climate models can only be created by using this broad data collection, which helps us understand the mechanisms of ongoing climate change and forms the basis for cross-border climate protection agreements, such as the Paris Agreement or the European Union's Green Deal.
