OSTM/Jason-2 - All instruments plus data animation

El Niño is characterized by unusually warm ocean temperatures in the eastern equatorial Pacific. The warmer water associated with El Niño displaces colder water in the upper layer of the ocean caus...

This visualization shows total sea level change between 1992 and 2019, based on data collected from the TOPEX/Poseidon, Jason-1, Jason-2, and Jason-3 satellites. Blue regions are where sea level ha...

Our planet is changing. Our ocean is rising. And it affects us all. That’s why a new international satellite will continue the decades-long watch over our global ocean and help us better understand...

The joint U.S.-European Sentinel-6 Michael Freilich is the next in a line of Earth-observing satellites that will collect the most accurate data yet on sea level and how it changes over time. With ...

TOPEX/Poseidon Ground Tracks

The Jason-3 satellite, launched on January 17, 2016, is allowing scientists to continue a 23-year record of crucial ocean monitoring.

Our World: How High is the Ocean?

For over 20 years NASA has been tracking the global surface topography of the ocean in order to understand the important role it plays in our daily lives. Climate change is causing our Ocean to war...

For NASA scientist Severine Fournier, studying our planet knows no borders.

Karl and Seymour learn how carbon dioxide is formed in this sketch from The Lollygaggers, a global warming sketch comedy.

After living in coastal Virginia and seeing the effects of climate change firsthand, Ben Hamlington is now researching sea level rise at NASA JPL.

This video discusses the water cycle, which is the movement of water around the Earth, and its importance to life. Changes to the water cycle affect climate and vice versa.

For NASA JPL engineer Parag Vaze, studying Earth’s rising ocean has been a career three decades in the making.

Earth’s rising seas are some of the most visible signs of our warming planet. Over the last 23 years, NASA satellite missions have observed a steady rise in global sea levels as polar ice sheets me...

A SpaceX Falcon 9 rocket lifts off from Space Launch Complex 4 at Vandenberg Air Force Base carrying the Jason-3 spacecraft. Liftoff was at 10:42 a.m. PST (1:42 p.m. EST).

Here we provide side by side comparisons of Pacific Ocean sea surface height (SSH) anomalies of what is presently happening in 2015 with the Pacific Ocean signal during the famous 1997 El Niño.

Jason-3 Animation

On Aug. 26, 2015 at 9:30 a.m. PT, NASA hosted a media teleconference to discuss recent insights on sea level rise and the continuing challenge of predicting how fast and how much sea level will ris...

Sea Surface Height 01/2006-04/2010

Earth’s global sea levels are rising – and are doing so at an accelerating rate.

A key ocean observation satellite has been named after Earth scientist Michael Freilich

Decades of Discovery - How altimeters help us every day.

NASA Climate Watcher Waves Goodbye

Sea level rise is an indicator that our planet is warming. When ice on land, such as mountain glaciers or the ice sheets of Greenland or Antarctica, melts, that water contributes to sea level rise.

NASA and its partners announced the renaming of the mission, previously known as Sentinel-6A/Jason-CS.
