Sentinel-4 dual spectrometers for continuous observation of the atmosphere
Airbus Defence and Space will be the European Space Agency’s (ESA) prime contractor for the development and construction of two highly accurate instruments designed to monitor the atmosphere.
The two Sentinel-4 mission spectrometers will for the first time gather data on the quality of the Earth’s atmosphere and its chemical composition from a geostationary orbit. Their position at an altitude of 36,000 kilometres will allow seamless observations of Europe and North Africa to be taken hourly.
