The PO.DAAC is pleased to announce the public release of the NASA-SSH Sea Surface Height from Standardized Reference Missions Only Version 1 datasets produced by NASA. Two distinct datasets are released. The datasets are produced from observations of sea surface height from the radar altimeter satellites in the reference mission orbits, including TOPEX/Poseidon, the Jason series, and Sentinel-6. All missions have been referenced to a common baseline, additional quality control has been performed, and errors with wavelengths around one orbital cycle have been reduced. More information regarding NASA-SSH is available from PO.DAAC’s NASA-SSH mission page.

Data in Action: The rate of global sea level rise doubled during the past three decades
Global Mean Sea Level time series from 1993 to 2023 from altimetry. Past and current altimetry measurements allow us to monitor global sea level and to make projections for the future. If the current trajectory continues, global sea levels will increase by more than 16.9 cm over the next three decades.
