资源简介：
Contents: gridded sea surface heights above geoid; dynamic topography is the
sum of sea level anomaly (SLA) and mean dynamic topography (MDT, Rio05 here)
Use: study of the general circulation (ocean gyres ...)
Global gridded data (1/3°x1/3° on a Mercator grid), available in near-real time
and in delayed time in NetCDF format.
In delayed time, two types of products are available:
- "Ref" (Reference) series: homogeneous datasets based on two satellites
(Topex/Poseidon, Jason-1 + ERS, Envisat) with the same groundtrack. Sampling is
stable in time.
- "Upd" (Updated) series: up-to-date datasets with up to four satellites at a
given time (adding GFO and/or Topex/Poseidon on its new orbit). Sampling and
Long Wavelength Errors determination are improved, but quality of the series is
not homogeneous.
Absolute geostrophic velocities are also available for gridded merged data.
Regional products with an improved quality are available in local areas
