X-TRACK, Along track Tidal Constants

The CTOH computes and distributes delayed-time regional along-track tidal constants estimated from its along-track 1Hz sea level anomalies (SLA) products. SLA time series have been computed with the X-TRACK processor for the whole Topex/Poseidon, Jason-1, Jason-2 and Topex/Poseidon interleaved, Jason-1 interleaved period applying the latest reprocessing CTOH standards. CTOH tidal constants product contains along-track estimates of amplitude, phase lag for each tidal constituent, that can be recovered locally with CTOH specific harmonic analysis software. Spatial locations of tidal estimates along the altimeter ground track are indicated in latitude and longitude variables. Contents: Along-track Sea Level Anomalies projected onto the reference tracks with a spatial interval of about 6-7 km between points (1 second). Specific processing (developed at LEGOS) has been made using the latest corrections available.
