资源简介：
Contents: along-track 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 ...)
The data are global mono altimeter satellite products, homogeneous with other
satellites, 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.
Regional products with an improved quality are available in local areas
