Twin satellites provide global coverage of Earth’s oceans

Today’s Video of the Day comes from the European Space Agency (ESA) and features a look at the Copernicus Sentinel-3 mission, which provides a wealth of information about Earth’s oceans.

The Sentinel-3A satellite was first launched in February 2016 and will soon be joined by its identical twin, Sentinel-3B. While the satellites can provide important data about land, ice, and the atmosphere, their marine applications are perhaps the most developed. The instruments can measure ocean temperatures for weather forecasting services, marine biological productivity, sea level changes, and ocean pollution.
