[OLD TEMPLATE] X-TRACK L2P : SEA LEVEL ANOMALIES DEDICATED TO COASTAL APPLICATIONS - Regional (23 areas)

The CTOH computes and distributes specific, coastal along-track sea level anomalies (SLA) using its X-TRACK processor over 23 regions, for all precise altimeter missions : Topex/Jason-1/Jason-2/Jason-3 (+ Interleaved orbits for Topex, Jason-1, Jason-2), ERS-1, ERS2, Envisat, SARAL/AltiKa, Geosat Follow On, HaiYang-2A and Sentinel-3A. The Sea Level Anomaly time series have been computed with the X-TRACK processing system (developed at CTOH/LEGOS) but, unlike the previous version of the X-TRACK dataset, this X-TRACK L2P dataset is computed from the Level 2 Plus (L2P) products distributed by CDS-SAT-AVISO. The X-TRACK L2P product is also more complete since in addition to the sea surface height anomalies, it contains the significant wave height and the backscatter coefficient. The applied altimetry corrections are also provided in this product.
