The first of two identical spacecraft, was successfully launched into Earth orbit on Saturday, 21 November 2020 to continue sea level observations for at least the next decade. The data from this mission is coming into the PO.DAAC, the official NASA archive for the Sentinel-6 Michael Freilich mission and physical oceanography data in general.
Globally-averaged, or global mean sea level (GMSL), has been accurately observed by satellite altimeters since the early 1990s. Sentinel-6 Michael Freilich will continue these observations after its launch on November 21, 2020.
This animation depicts gridded, daily volumetric water content estimated for the 0-5 cm surface soil layer between March 2017 and August 2020.
According to the United Nations, 40% of the world's population lives within 100 km of a coast, meaning that close to three billion people could be impacted by changes in sea level.
The new Sea Level Change Data Pathfinder highlights the diversity of datasets used to piece together the status and drivers of sea level rise.
