Wave and wind along-track altmetry products (level3) NRT

Along-track significant wave height (SWH) and wind speed modulus for the following missions : CFOSAT (nadir), Sentinel-3A, Sentinel-3B, Jason-3, Saral-AltiKa, Cryosat-2 and HY-2B in Near-Real Time (NRT) for a global coverage (-66°S/66+N for Jason-3, -80°S/80°N for Sentinel-3A and Saral/AltiKa).

SWH measurements are computed from the leading edge of the altimeter waveform. For Sentinel-3A and 3B, they are deduced from the SAR altimeter.

One file containing valid SWH is produced for each mission and for a 3-hour time window. It contains the filtered SWH (VAVH), the unfiltered SWH (VAVH_UNFILTERED) and the wind speed (wind_speed).

Statement
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)
