The 1/3 degree Mercator gridded weekly merged sea-level anomalies (SLAs) data set is distributed by archiving, validation and interpretation of Satellite Oceanographic data (AVISO). SLA were merged from four satellite missions (TOPEX/Poseidon, ERS-1/2, Jason-1 and ENVISAT) using the
optimum interpolation technique (Le Traon et al., 1998).
The horizontal resolution of SLA maps is sufficient to investigate
mesoscale eddies with horizontal scales from 100 to 200 km.
