The new OSTM/Jason-2 OGDR will start on 15 December on Eumetsat and Noaa Services.

The Operational Sensor (Geophysical) Data Record (OSDR/OGDR) is a new, real-time operational product specially developed for the Jason-2 mission. The OSDR/OGDR will be the faster product delivered to the users, with a short delay of 3 - 5 hours. It is processed by the operational agencies partners, Noaa and Eumetsat. Note that this is a non-validated product that uses orbits computed by the on-board Doris Navigator (DIODE) and that it does not contain all the environmental/geophysical corrections.

The real-time operational product comprises three Jason-2 OGDR products:

• A nominal product, containing sea surface height, significant wave height and ocean surface wind speed parameters, in NetCDF format, see <link internal-link>OGDR near-real time page product
• A BUFR format version of the the nominal product, see <link internal-link>OGDR near-real time page product.
• A reduced product containing mean sea surface parameters, in NetCDF format, see <link internal-link>OGDR-SSHA.

Other OSTM/Jason-2 data (in near-real time -IGDR- and delayed time -GDR-) will remain restricted, as long as the Calibration/Validation phase will last.
