Earth from Space: Special edition · 8:03 · Video: European Space Agency, ESA · Watch at the source

In short: Explore how advanced satellite technology monitors Earth's physical changes. This special edition features insights from leading scientists on the progress of radar altimetry and the future of global observation.

Anny Cazenave appears in this clip; she serves as a Senior Scientist and altimetry expert for CNES plus the LEGOS research centre. Speaking at a symposium in Venice in September 2024, she discusses two decades of progress in radar altimetry.

To describe next year's Earth observation objectives, Professor Volker Liebig, who leads ESA’s Earth Observation Programmes, also takes part. These perspectives provide a look into how satellite data informs our understanding of global geophysical and oceanographic changes.
