Data Description

    Ocean Surface Topography Mission (OSTM)/Jason-2 and 3: Telemetry, 2008-present (NODC Accessions 0044986 and 0122599) - The Ocean Surface Topography Mission (OSTM)/JASON-2 and JASON-3 are follow-on missions continuing the TOPEX/Poseidon and JASON-1, and were designed to ensure continuity of high quality measurements for ocean science and to provide operational products for assimilation and forecasting applications. The missions are joint effort by National Oceanic and Atmospheric Administration (NOAA), European Organization for the Exploitation of Meteorological Satellites (EUMETSAT), France’s Centre National d’Études Spatiales (CNES) and National Aeronautics and Space Administration (NASA). 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. The development of the JASON-3 mission, and related Ground Segment, is based on a recurrent JASON satellite and ground system with a similar partnership scheme to JASON-2. The JASON-3 satellite is planned to be launched in 2016. The satellite will be placed in the same orbit as JASON-2. This collection of data contains OSTM/JASON-2 and JASON-3 telemetry data. Dataset consists of raw Level-0 telemetry data from the satellite spacecraft. There are three datatypes produced: 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-3/3B, 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. Jason-2 telemetry data are archived at the NOAA National Centers for Environmental Information (NCEI) as NODC accession number 0044986 ( Jason-3 telemetry data will be archived at the NOAA National Centers for Environmental Information (NCEI) as NODC accession number 0122599 ( These data are subject to access restrictions.
