Since the first Mean Dynamic Topography dataset disseminated through Aviso, 15 years have gone by with several upgrades issued, and many improvements in quality and in the method used.

Altimetry enables to follow and understand the sequence of events leading to monsoon onset, in conjunction with other remote sensing data

Satellite Radar altimetry can also measure ice topography over huge icebergs thus monitoring their melt and fragmentation

A better knowledge of internal tides, both coherent and incoherent, is primordial for SWOT altimetry mission. A study in the Solomon Sea shows the complexity in predicting internal tides.

Fifty years ago, a meeting took place in Williamstown, USA, where the possibilities for observing the Earth (solid and ocean), including from space, were discussed. Altimetry was much recommended.

Wave power, taking into account both the wave heights measured by altimetry and their periods has increased globally

SWOT will provide brand new capabilities for hydrological measurements and studies. Preparation are ongoing, especially concerning the discharge estimation which will be part of the river products

A multidata combined approach is a unique way to obtain a complete picture of a system as complex as the Liguro-provençal current.

Swot will enable to see both the temporal variations and the spatial complexity of the Pantanal wetlands' flooding, the largest tropical wetlands on Earth

SAR-altimetry mode implemented onboard Sentinel-3 can be further refined so as to reach 50 cm resolution along-track.

Using the physical parameters of the environment, in particular from altimetry satellites, coupled with animal tracking, we can better understand, and thus protect, marine life.
