Airbus Defence and Space has delivered the first Sentinel-5 instrument to the European Space Agency (ESA) for integration on the MetOp Second Generation Satellite A. The UVNS (Ultraviolet Visible Near-infrared Short-wave infrared Spectrometer) instrument will enhance monitoring of air quality, ozone layer changes, and wildfire emissions. Sentinel-5 is one of the “atmospheric sentinels” designed to monitor the composition of Earth’s atmosphere and support the EU’s Copernicus climate monitoring programme. EUMETSAT, the European Organisation for the Exploitation of Meteorological Satellites, will operate both the spacecraft and the instrument.
