Abstract:

This dataset contains gridded sea level anomaly data and surface geostrophic current components from 1993-01-01 to 2017-05-17. Daily means of sea surface height, zonal velocity U, and meridional velocity V are gridded at 0.25 x 0.25-degree resolution. The data were sub-setted from the multi-mission gridded data hosted at Copernicus Marine and Environment Monitoring Service (CMEMS, formerly distributed by Aviso). The surface currents can be compared with subsurface currents from mooring observations, available in companion dataset under GRIIDC Unique Dataset Identifier (UDI) R6x.820.000:0001 (DOI: 10.7266/n7-7g3d-9q79).

Data Parameters and Units:

Geostrophic velocity ug (zonal) [m/s], geostrophic velocity vg (meridional) [m/s], longitude [degrees], latitude [degrees], t (day of observation) [days since 1993-01-01], t_date (time date string).

Methods:

A subset of gridded sea surface height is extracted from a global dataset provided by Copernicus Marine Environment Monitoring Service (CMEMS).

Instruments:

Satellite altimeters.
