Copernicus Sentinel-4 will monitor air quality, trace gases and aerosols over Europe at high spatial resolution every hour during the day.

The Sentinel-4 instrument, the Ultraviolet Visible Near-infrared (UVN) spectrometer, will be carried on EUMETSAT’s Meteosat Third Generation Sounder satellites in geostationary orbit.

It will work with the onboard InfraRed Sounder (IRS) to monitor ozone, nitrogen dioxide, carbon monoxide, sulphur dioxide and other trace gases.

The data will be used by the Copernicus Atmosphere Monitoring Service (CAMS) and will support air quality, pollution and climate monitoring.

Ultraviolet Visible Near-infrared (UVN)

The UVN is a spectrometer that measures in the ultraviolet (UV: 305–400nm), the visible (VIS: 400–500nm) and the near infrared (NIR: 750–775nm), with a spatial sampling resolution of around 8km.
