When a satellite by the name of Sentinel-6 Michael Freilich launches this November, its primary focus will be to monitor sea level rise with extreme precision. But an instrument aboard the spacecraft will also provide atmospheric data that will improve weather forecasts, track hurricanes, and bolster climate models.
"Our fundamental goal with Sentinel-6 is to measure the oceans, but the more value we can add, the better," said Josh Willis, the mission's project scientist at NASA's Jet Propulsion Laboratory in Southern California. "It's not every day that we get to launch a satellite, so collecting more useful data about our oceans and atmosphere is a bonus."
A U.S.-European collaboration, Sentinel-6 Michael Freilich is actually one of two satellites that compose the Copernicus Sentinel-6/Jason-CS (Continuity of Service) mission. The satellite's twin, Sentinel-6B, will launch in 2025 to take over for its predecessor.
Together, the spacecraft will join TOPEX/Poseidon and the Jason series of satellites, which have been gathering precise sea level measurements for nearly three decades. Once in orbit, each Sentinel-6 satellite will collect sea level measurements down to the centimeter for 90% of the world's oceans.
