New PO.DAAC animation now available!
Animation of the retrieved ocean surface wind speed (meters per second) over the period of 1 August 2018 to 31 December 2020.
Data in Action: Glaciers Melt from Below
Greenland’s glaciers have been rapidly melting over the past several decades, and are now a major contributor to global sea level rise.
New PO.DAAC animation now available!
Animation of sea surface salinity from 31 March 2015 to 9 November 2020 based on the 8-day running mean version 5.0 Level 3 NASA Soil Moisture Active Passive (SMAP) dataset from JPL.
Sentinel-6 Michael Freilich Satellite Now in Orbit
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.
New Data in Action: Globally Averaged Sea Level
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.
New PO.DAAC animation now available!
This animation depicts gridded, daily volumetric water content estimated for the 0-5 cm surface soil layer between March 2017 and August 2020.
Sea Level Change Data Pathfinder
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.
Solving the Data Puzzle of Sea Level Rise
The new Sea Level Change Data Pathfinder highlights the diversity of datasets used to piece together the status and drivers of sea level rise.
New PO.DAAC animation now available!
Animation of the retrieved ocean surface wind speed over the period of 1 August 2018 to 22 October 2020, produced using the CYGNSS Level 3 Science Data Record (SDR) Version 3.0 dataset.
