25 years of progress in space altimetry
Today’s Video of the Day from the European Space Agency comes to us from the Azores, the site of the 25 Years of Progress in Radar Altimetry Symposium.
Satellite altimeters have shown that the volume of the ocean is rising at an average of three millimeters per year, but this rate is now very quickly approaching five millimeters per year.
Satellite altimetry is not only used to monitor sea-level rise, but is also used to measure ocean currents and changes in ice sheet elevation.
