This accession contains the data descriptions for the OSTM/Jason-2 Ancillary data files, which is served through the NOAA/NESDIS Comprehensive Large Array-data Stewardship System (CLASS): http://www.class.noaa.gov

OSTM/Jason-2 is a follow-on mission to Jason-1, which takes over and continues the TOPEX/Poseidon and Jason-1 missions. OSTM/Jason-2 involves Centre National d'Etudes Spatiales (CNES), NASA and 2 new partners: the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) and NOAA in order to 1) ensure continuity of high quality measurements for ocean science, and 2) provide operational products for assimilation and forecasting applications. OSTM/Jason-2 was launched on 20 June 2008 and reached its nominal repetitive orbit on 4 July 2008. The start of cycle 1 occurred on 12 July 2008.

These Ancillary data files are used to generate Level-2 products. They include both static tabular data files and dynamic files which change/grow over time. They are mission specific files used in the production of Level-2 products. All members of the Ancillary data family (J2-ANC) were made unrestricted on 15 December, 2008.

Other data/products associated with OSTM/Jason-2 are also provided through CLASS. They are: Level-2 Geophysical Data Records (GDRs), auxiliary data files used to generate Level-2 products, quality reports from the near real-time altimetry validation system (NRTAVS), orbit information of JASON-2 satellite and telemetry data. The descriptions of these data products can also be accessed in other accessions at NODC.

Telemetry - Dataset consists of raw Level-0 telemetry data from the Jason-2 spacecraft. There are three datatypes available: Housekeeping Telemetry - Recorded (HKTM-R) is stored on the spacecraft for later downlink; Payload Telemetry 1 (PLTM-1) is the payload science data from the core-mission payloads: Poseidon-3, DORIS, AMR, and GPSP; and Payload Telemetry 2 (PLTM-2) is the payload science data from the passenger mission of opportunity payloads: CARMEN-2, L2T2 and LPT. They are available as CCSDS packet files. 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.

Other data/products associated with OSTM/Jason-2 are also provided through CLASS. They are: Level-2 Geophysical Data Records (GDR), ancillary and auxiliary data files used to generate Level-2 products, quality reports from the near real-time altimetry validation system (NRTAVS) and orbit information of Jason-2 satellite. The descriptions of these data products can also be accessed in other accessions at NODC.

These auxiliary data files are used to generate Level-2 products.They Include both static tabular data files and dynamic files which change/grow over time. Auxiliary files are produced outside of OSTM but are used in the production of Level-2 products. Filetypes in the Auxiliary data family (J2-AUX) which are produced by the European Center for Medium range Weather Forecasting (ECMWF) are restricted by ECMWF to the Jason-2 project team.

These files are produced by CNES for offline (IGDR, GDR) data production. For GPSP1, intermediate level-1 data files are in "RINEX" format and from the Global Positioning System (GPS) receiver and are used to compute precise GPS orbits for the spacecraft. For TLE: Two Line Element files are used to determine the position and velocity of the satellite. Within CLASS, they will be used directly to determine each orbit's equator crossing longitude and time which subsequently are used to support spatial search. For MOE and POE, medium-precision and precision orbital ephemeris files are from the DORIS system. All members of the Orbital Information family were made unrestricted on 15 December, 2008.

Other data/products associated with OSTM/Jason-2 are also provided through CLASS.
