Monitoring the marine environment and atmospheric composition
Sentinel-3 is a dedicated Copernicus satellite mission delivering a variety of high-quality ocean and atmosphere measurements.

The mission's main objective in support to the marine environment is to determine parameters such as sea-surface topography, sea-surface temperature and ocean surface colour. It provides two day global coverage optical data (with two satellites), as well as altimetry measurements, for sea and land applications with real-time products delivered in less than three hours. The instruments also provide a view on the atmosphere, including information on air quality and fires. The satellites are operationally managed from the EUMETSAT Sentinel-3 Marine Centre.
Sentinel-3 instruments and ground segment
Sentinel-3 altimetry instruments
Three instruments are used for the altimetry mission to measure sea surface heights.
Sea and Land Surface Temperature Radiometer (SLSTR)
SLSTR measures thermal radiation and uses a dual view technique.
Altimetry data is used to determine sea level height, wind speed and wave height.
Ocean colour services
Providing information on ocean living ecosystems, water quality and sediment dynamics.
The Copernicus Sentinel-3 mission includes key optical instruments monitoring the composition of our atmosphere.
