Ocean Surface Topography Mission (OSTM) /Jason-2: Telemetry (NODC Accession 0044986)

Metadata Updated: February 27, 2019

This accession contains the data descriptions for the OSTM/Jason-2 Telemetry data, 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.

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.
