The Copernicus Sentinel-3A satellite has been systematically measuring our oceans, land, ice and atmosphere since its launch in February 2016. The satellite will soon be joined in orbit by its identical twin, Sentinel-3B. Once in orbit, both satellites will provide global coverage every two days.

For over two years, Sentinel-3A has been gathering data on land cover vegetation health and the oceans. Its unique information is already feeding a range of practical applications.It is used for monitoring and understanding large-scale global dynamics such as marine pollution, sea level changes, and aquatic biological productivity.

“Sentinel-3 and land-surface radiometer are providing us with the best sea temperatures in the world, and these are helping us to understand coral bleaching. Together with the satellite’s ultra-instrument, we can look at the ocean color and how the marine productivity is responding to changes in the climate,” says Craig Donlon, Sentinel-3 mission scientist.

Overland, Sentinel-3 also has excellent potential. The mission monitors wildfires, maps the way land is used, provides indices of vegetation state, and measures the height of rivers and lakes – complementing the high-resolution measurements of its sister mission Sentinel-2.

Soon, these services will be further enhanced with the launch of the Sentinel-3B satellite, expected for the end of April.
