on the physical phenomena that are to be studied. They
include the oceanic tides, the wind and atmospheric pressure
effects, the solid tide, the polar tide, the loading effect
and the sea state bias (SSB). For the determination of the
altimeter bias, the maximum of known signals must be
retrieved from the altimeter SSH in order to eliminate as
many sources of errors as possible that could explain a bias
of several centimetres. The geophysical corrections used in
this study are presented in the Section 3.3
