Mozambique area (M)SLA - (Map of) Sea Level Anomalies & geostrophic velocity anomalies

Types of dataset: Ssalto/Duacs multimission altimeter products
Contents: multimission sea surface heights computed with respect to a twenty-year mean, along-track or gridded with a 1/8°x1/8° spatial resolution on a cartesiangrid.
Use: regional studies; ocean variability (mesoscale circulation, seasonal variation...), including operational oceanography (near-real time products)
Condition of access: Ssalto/Duacs gridded geostrophic velocities products are devoted to scientific applications and non-commercial use (conditions of use are detailed in the licence agreement).  All Ssalto/Duacs product users need an account, see Access to Ssalto/Duacs data.
Data access service: see Data access service. FTP delivers the gridded and along-track data (the most recent data day-0 in NRT). Whereas the Opendap/geographic-temporal extraction tool/LAS only delivers gridded data more than one month.
Description: regional product resulting from specific processes, available in near-real time. 
For gridded merged data, each map represents the sea state for a given day as a snapshot of the ocean. A formal mapping error variable is also available in the MSLA file. Geostrophic velocity anomalies are delivered in a specific file.
Geographic coverage: Mozambique area (30.0625°E, 59.9375°E / -29.9375°S)
Format: NetCDF-CF
Tools :

NRT-(M)SLA

Description : MSLA heights and geostrophic velocities grids are delivered daily through the FTP (6-day delay, a 3-day delay and a 0-day delay ) whereas Opendap/Gridded Data Extraction Tool/LAS only deliver maps more than one month. Only the "all sat merged" version is available 
SLA along-track files are delivered daily through the FTP (only "filtered" version or "vfec")
Data period : within a few months at most, from the latest update of the DT products to today.
