Coastal Tide - X-TRACK

Amplitude of the M2 tidal constituent in meters over the region North East Atlantic (NEA)/ Credits CNES/CTOH.

Types of dataset: auxiliary products
Contents: regional along-track tidal constants products for long time series missions.
Use: coastal oceanography, tides model
Description: the regional along-track tidal constants are computed from regional Sea Level Anomalies X-TRACK for 73 tidal constituents by using harmonic analysis, for long time series missions (Topex/Poseidon+Jason-1+Jason-2 and Topex/Poseidon interleaved +Jason-1 interleaved).
The X-TRACK Tidal Constant is a new added-value coastal altimetry product. It provides accurate along-track tidal constant estimates at regional scale and includes all coastal seas in the world. This product usefully completes tide gauge observations for tidal studies, the validation of tidal models or data assimilation into models.
