Abstract

The dataset contains satellite-derived sea-surface height measurements collected by means of the TOPEX/Poseidon/ERS, JASON-1/Envisat, and Jason-2/Envisat satellite sensors. Reprocessed science quality monthly and weekly delayed data is collected when available from AVISO, Near-real time data is collected daily is available as weekly 7-day composites. All data is at a spatial resolution of approximately 0.25 degrees. The geographic coverage is global, and the temporal coverage ranges from 1993-present. The data is combined with a Niiler Climatology (Niiler et al., 1994) to obtain absolute sea surface heights.

Geostrophic currents (u and v components) are mathematically derived, and available at a spatial resolution of 0.5º.
