Measuring El Niño & La Niña - JPL Open House '99 Display

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...

Jason-1 Measurement System

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...

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

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

Jason-1 and TOPEX/Poseidon Bookmark

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

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...
