The Sentinels are a family of missions developed by ESA for the operational needs of the Copernicus programme. Each mission, carrying a different range of technologies, will focus on various aspects of Earth Observation: Atmospheric, Oceanic, and Land monitoring, and the data will be of use for a broad range of applications.

Sentinel-3 carries multiple instruments to measure sea-surface topography, sea- and land-surface temperature, and ocean- and land-surface colour, with the main objective to support ocean forecasting systems, environmental monitoring and climate monitoring.

Data available from ONDA are provided by ESA and the European Commission

Mission Details

Launch: Sentinel-3A on 16 February 2016, Sentinel-3B on 25 April 2018

Orbit: Polar, Sun-synchronous at altitude of 815 km

Revisit time: Sentinel-3 is a constellation of two satellites which will be orbiting 140° apart. One satellite provides a revisit time of 27 days (385 orbits).

Ocean and Land Colour Instrument (OLCI)
Sea and Land Surface Temperature Radiometer (SLSTR)
Synthetic Aperture Radar Altimeter (SRAL)
Microwave Radiometer (MWR)

Main applications: Sea-level change & sea-surface temperature mapping, water quality management, sea-ice extent and thickness mapping; land-cover mapping, vegetation health monitoring; glacier monitoring; water resource monitoring; wildfire detection; numerical weather prediction.
