Global monitoring - Sentinel-3

ESA is preparing the Sentinel satellites as part of the EU’s Global Monitoring for the Environment and Security initiative.

Sentinel-3 is a multi-instrument mission to determine parameters such as sea-surface topography, sea- and land-surface temperature, ocean colour and land colour with high-end accuracy and reliability.

Near-real time data processing and delivery will allow a broad range of GMES services including maritime safety services that need ocean-surface wave information, surface temperature and data to improve ocean current forecasting systems; sea-water quality and pollution monitoring requiring advanced ocean colour products in both open ocean and coastal oceanographic application areas; sea-ice charting services requiring sea-ice extent and ice-berg detection; services to monitor land-use change, forest cover, photosynthetic activity, soil quality and fire detection.
