TOPEX/Poseidon Measurement System

La Niña Series

Launched on January 17, 2016, Jason-3 is a partnership that includes NOAA, NASA, CNES, and EUMETSAT.  The map shown here was generated using sea surface height measurements from the first 10 days (...

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

It’s not only water processes that play a role in global sea level rise – ground movements can play a significant role as well.

For NASA engineer Shannon Statham, building spacecraft is all about being creative.

El Niño Series

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

El Niño/La Niña

Applications of Spaceborne Altimetry

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...
