Περίληψη | An absolute sea-level monitoring and altimeter calibration permanent facility has been established on the isle of
Gavdos, 50 km south of the island of Crete, Greece. This calibration/validation facility has been chosen because
Gavdos is under a crossing point of the ground-tracks of Jason-1 satellites, and adjacent to an Envisat pass.
Satellite altimeter missions are evaluated at that site using external measurements from tide gauges, GPS,
a DORIS beacon, meteorological sensors, wave-height sensors, airborne campaigns for gravity and sea-surface
topography, water-vapour radiometry, solar atmospheric spectrometry, GPS buoys, altimeter transponder, Satellite
Laser Ranging, etc. The mean sea level and the earth’s tectonic deformation field in the region have also
been determined accurately.
Comparison over the cycles 70 to 77 of the Jason-1 satellite indicate that its absolute mean bias for the
sea-surface heights is 134 mm ±20 mm. The GAVDOS project has started in December 2001 and has been in
the context of an international calibration/validation effort of the Jason-1 Science Working Team. | en |
