TOPEX/Poseidon Instruments

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.

Launching aboard the joint U.S.-European Sentinel-6 Michael Freilich satellite is NASA’s next instrument that will help improve weather forecasting.

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

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...

The Jason-2 satellite sees something brewing in the Pacific. Researchers say it could be a significant El Niño with implications for global weather and climate.

A look at how NASA is dealing with the threat of sea level rise to its coastal infrastructure.

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

Jason-CS/Sentinel-6 - How they will work

On the left is Sea Surface Height Anomalies (SSHA) relative to the sea level mean (1993-2018). On the right is Global Mean Sea Level (GMSL) with the sea level trend as the straight line. The data a...

Sentinel-6 Michael Freilich will join a long-standing family of Earth observing satellites from NASA and European partners.

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.

Decades of Discovery - How altimeters help us every day.

NASA and its U.S. and international partners have teamed up to launch a new Earth-observing satellite called Sentinel-6B that will measure sea surface height of most of the planet’s ocean. These ob...

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...

Sentinel-6 Michael Freilich Launch footage

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...

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

Recorded live broadcast of Sentinel-6B, launched at 9:21 p.m. PST, Sunday, Nov. 16 (12:21 a.m. EST, Monday, Nov. 17) aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California.

Oceans of Climate Change

Growing up in landlocked Zimbabwe, NASA JPL engineer Shailen Desai was far from the ocean but still experienced its effects on the climate. Now, he is contributing to an international effort to tra...

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...
