Regional SLAext - extended Sea Level Anomalies
North East Atlantic & Gulf of Mexico
Types of dataset: Ssalto/Duacs multimission altimeter products
Contents: multimission along-track sea surface heights computed with respect to a seven-year mean
Use: regional studies; ocean variability (mesoscale circulation, seasonal variation...), including operational oceanography (real-time products).
Condition of access : All Ssalto/Duacs product users need an account on FTP, see <link fr donnees informations-sur-les-produits duacs access-ssaltoduacs-products index.html _blank>Access to Ssalto/Duacs data
Description: regional product resulting from specific processes, available in near-real time (i.e each day) and in delayed time. These products are delivered with high frequency, ocean tide and inverse barometer corrections. The first two corrections were applied in the SLA computation; the third correction is provided for users who want to use the "conventional" inverse barometer in place of the more precise high frequency correction.
Geographic coverage: 30°N-70°N, 45°W-20°E (North East Atlantic); 18°N-31°N, 80°W-101°W (Gulf of Mexico)
Format: NetCDF, NetCDF CF1.4 (for the along-track products)
