When the ocean dynamics correction is applied, the differences
in Ajaccio are increased by nearly 1 cm more.
Some further investigations (not presented here) show that
this behaviour is linked to the oceanic tide contribution,
rather than the DAC. Moreover, the same increase is visible
when using the FES2004 global model. The differences
are amplified up to 2 cm when retrieving the tidal signal in
Ajaccio with a harmonic analysis, which is due to the badquality
data. The Ajaccio tide gauge being installed in the harbour facilities, in a steep-sided area, the tidal signal
observed by the instrument is complex and difficult to
model accurately
