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...

Altimeter Applications - JPL Open House '99

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 (...

Greenland and Antarctica are home to most of the world's glacial ice – including its only two ice sheets – making them areas of particular interest to scientists.

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...
