The findings presented at the ‘20 Years of Progress in Radar Altimetry’ symposium in Venice, Italy show archived data from radar altimeters on the ERS-1, ERS-2 and Envisat satellites which observed the wave-like motion around the centre of the Lofoten Basin. Radar altimeters onboard provide precise measurements of sea-surface height, as well as freshwater bodies, land and ice.
The ERS-1/2 and Envisat measurements enabled the provision of sea-surface height with an accuracy of a few centimetres from their orbits around 800 km above Earth.
