The Ocean Surface Topography Mission (OSTM)/Jason-2 is a follow-on altimetric mission to the very successful TOPEX/Poseidon mission and Jason-1. It is a joint mission between NASA and CNES (French space agency). It launched 20 June 2008 and began data collection on 12 July 2008. OSTM is capable of measuring significant wave height, sigma naught (sigma0), dry and wet troposphere and ionosphere, which can be used to calculate sea surface height and anomalies and total electron content.
OSTM has a repeat period of approximately 10 days with 254 passes per cycle.
Lists of cycle start times, maneuvers performed to maintain orbit, sateholds and periods of no data collection are provided in the "Related Links" sidebar.
