Minimize Sentinel 4


Sentinel-4 is dedicated to atmospheric monitoring, and will consist of payloads carried aboard EUMETSAT's Meteosat Third Generation satellites.

The mission aims to provide continuous monitoring of the composition of the Earth's atmosphere at high temporal and spatial resolution and the data will be used to support monitoring and forecasting over Europe.

The mission will utilise two sensors, UVN and IRS, and EUMETSAT's FCI, aboard the MTG-Imager satellite, will provide additional data for the mission.
