The XTRACK 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.

Computed by the Centre of Topography of the Oceans and the Hydrosphere (CTOH), the regional XTRACK Tidal Constant product is estimated from the regional XTRACK Sea Level Anomalies for 73 tidal constituents by using harmonic analysis and for long time series missions (Topex/Poseidon+Jason-1+Jason-2 and Topex/Poseidon interleaved +Jason-1 interleaved).

PROCESSING:

The details about processing can be found in the product page and in the handbook.
