Coastal Products

Regional Products


The CTOH computes and distributes specific, coastal products:

          • One hertz along track Sea Level Anomaly : SLA 1Hz
          • High frequency Sea Level Anomaly : SLA HF
          • Mean Sea Surface : MSS
          • One hertz along track tidal constants: Tidal Constants


using its X-TRACK processor for all precise altimeter missions : Topex/Poseidon (TP), Jason-1 (J1) , Jason-1 interleaved (J1N), Topex/Poseidon interleaved (TPN), Jason-2, Geosat Follow on (GFO), Envisat and SARAL/ALTIKA  (click here to view available missions and the temporal coverage of each one).




Please do not forget to mention the following sentence in all publications or communications referring to a work based on the CTOH/LEGOS altimetry dataset:

"Altimetry data used in this study were developed, validated, and distributed by the CTOH/LEGOS, France".
