A FIDUCIAL REFERENCE SITE FOR SATELLITE ALTIMETRY IN CRETE, GREECE

摘要

With the advent of diverse satellite altimeters andrnvariant measuring techniques, it has become mature inrnthe scientific community, that an absolute referencernCal/Val site is regularly maintained to define, monitor,rncontrol the responses of any altimetric system.rnThis work sets the ground for the establishment of arnFiducial Reference Site for ESA satellite altimetry inrnGavdos and West Crete, Greece. It will consistently andrnreliably determine (a) absolute altimeter biases and theirrndrifts; (b) relative bias among diverse missions; but alsorn(c) continuously and independently connect differentrnmissions, on a common and reliable reference and alsornto SI-traceable measurements. Results from this fiducialrnreference site will be based on historic Cal/Val siternmeasurement records, and will be the yardstick forrnbuilding up capacity for monitoring climate change.rnThis will be achieved by defining and assessing anyrnsatellite altimeter measurements to known, controlledrnand absolute reference signals with different techniques,rnprocesses and instrumentation.
