Altimetry applications in videos : Mean Sea Level Rise

Almost three quarters of the Earth’s surface are covered by oceans: oceans are a key-element of our global climate system. It is a reality, the oceans respond to climate change: as a result of human activity and greenhouse gases, the climate is warming, the ocean expands and its level rises. Oceans are under close surveillance at all times: altimetry satellites accurately measure the sea level with a homogeneous and continuous global coverage since the launch of Topex-Poseidon in 1992.

The Jason-3 mission will soon complement this satellite constellation currently in flight by providing continuity of measurements that is essential for observing climate change.
