Jason-3 and Jason-2 mission performance
Event: 2018 Ocean Surface Topography Science Team Meeting
Session: Regional and Global CAL/VAL for Assembling a Climate Data Record
Presentation type: Poster
TOPEX/Poseidon, Jason-1, Jason-2, and then Jason-3 have allowed to build a high-precision ocean altimetry data record on historical ground track. Two altimeters of those are still in flight (Jason-2 and Jason-3). Their data are analyzed and monitored in order to assess the quality of the products.
Over the last 2 years many events occurred on Jason-2 mission. A first move of orbit occurred in October 2016 from TOPEX/Jasons historical ground track to the interleaved with Jason-3 one at the same altitude. In July 2017, Jason-2 was moved to a Long Repeat Orbit (LRO), approximately 27 km below the previous orbit still used by Jason-3. Since this date, SHM has occurred twice (in September 2017 and February 2018). How are the system performance and data quality affected (or not) by these events?
Since May 17th, 2017, Jason-3 is the only satellite on the TOPEX/Jasons historical ground track. A precise knowledge of Jason-3 data quality and errors is a key activity to ensure a reliable service to scientists involved in climate change studies as well as operational oceanography. We aim at presenting the overall performance of Jason-3 mission through different metrics highlighting the high-level accuracy of this mission.
