Abstract
Gridded product, provided in delayed time. As a snapshot, each map represents the sea state for a given day. One level of resolution is available (1/3°x1/3°, Mercator grid), but this product is also provided in a second version that is resampled on a 1/4°x1/4° cartesian grid (really destinated to users confused by the Mercator grid). This delayed time product is available in two versions:
- "Ref" (Reference) series: homogeneous datasets based on two satellites (Jason-2 / Envisat or Jason-1 / Envisat or Topex/Poseidon / ERS) 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 (Jason-2 / Jason-1 / Envisat from 2009 or between October 2002 and September 2005, the association Jason-1 / Topex/Poseidon / Envisat / GFO). Sampling and Long Wavelength Errors determination are improved, but quality of the series is not homogeneous.
