Purpose The objective of Sentinel-4 is to monitor key air quality trace gases and aerosols over Europe at high spatial resolution with a fast (hourly) revisit time in support of the GMES Atmosphere Service. The objective of the LEO missions, S-5 and S-5P, is to measure daily at global scale and high spatial resolution air quality and climate related trace gases and aerosols in the Earth’s atmosphere. The target species including O3, NO2, SO2, HCHO and aerosols shall be observed to support operational services covering air-quality near real-time applications, air-quality protocol monitoring and climate protocol monitoring. The S-4 system consists of an Ultra-violet Visible Near-infrared (UVN) imaging spectrometer embarked on EUMETSAT’s geostationary MTG-S platforms and relies on the utilization of subsets of data from EUMETSAT’s IRS sounder on-board the same platforms and from EUMETSAT’s FCI imager on-board the MTG-I platforms. S-5 UVN and SWIR (UVNS) is planned to be embarked on EUMETSAT’s EPS-SG series of satellites, while S-5P will fly on a dedicated platform.

Lineage The Sentinel-4 (S-4) mission within the context of Copernicus represents the geostationary component of European (EC, ESA) operational atmospheric composition monitoring missions.
Additional Information In December 2007, the GMES Atmospheric Service Implementation Group of the EC (European Commission), issued its preliminary recommendations for the development of the GMES Space Segment operational capabilities in regard of atmospheric missions. In particular, it recommended implementing the Sentinel-4 mission as a UVN (UV/Visible/Near-infrared) sounder to be deployed on the two MTG Sounding (MTG-S) satellites.
