Category: News of the Jason-2 mission, Operational news

In the frame of a cooperation between Cnes, Eumetsat, Nasa and Noaa, OSTM/Jason-2 takes over and continues Topex/Poseidon and Jason-1 missions. After the near real-time data release last December (OGDR) on Eumetsat and Noaa services, The IGDR dara are now available on Aviso and Noaa servers.

The IGDR family of files are datasets produced within two calendar days. They are produced solely by Cnes. These data are not fully validated (elementary and automatic controls only) and are derived from Doris data with the processing of a preliminary orbit. The environmental and geophysical corrections (preliminary for some of them) are included.

Three types of files are available with increasing size and complexity:

  • a <link internal-link>IGDR native NetCDF formatted datasets which contain 1Hz records as well as 20 Hz high-rate values;
  • a reduced 1Hz subset of the full dataset (<link internal-link>IGDR-SSHA);
  • an expert sensor product containing the full radar-echo waveforms (<link internal-link>S-IGDR);
