J2-AUX - OSTM/Jason-2: Auxiliary Files

Data Usage Guidance/Restrictions

Access restrictions on the Operational Geophysical Data Records were lifted on 15 December, 2008.
Restrictions on the Interim Geophysical Data Records were lifted on 15 January, 2009. Restrictions on the
Geophysical Data Records will be lifted after the June 2009 Ocean Surface Topography Science Team
meeting, which serves as the final Jason-2/OSTM product verification workshop.

All members of the Ancillary data family (J2-ANC), Orbital Information family (J2-ORBINFO), and Quality
Assurance reports family (J2-QA) were made unrestricted on 15 December, 2008.

Filetypes in the Auxiliary data family (J2-AUX), which are produced by the European Centre for Medium-Range
Weather Forecasts (ECMWF), are restricted by ECMWF to the Jason-2 project team. All telemetry data
(J2-TEL) are restricted to the project team, per the mission's 4-partner Memorandum of Understanding.
For these restricted data families, users will only see listed those datatypes upon which they can search.

UTC

Coordinated Universal Time (UTC) is the international time standard. It is the current term for what was
referred to as Greenwich Meridian Time (GMT). Zero (0) hours UTC is midnight in Greenwich England, which
lies on the zero longitudinal meridian. Universal time is based on a 24 hour clock, therefore, afternoon hours
such as 4 pm UTC are expressed as 16:00 UTC (sixteen hours, zero minutes).
