OSTST meeting, Wiesbaden, Germany: June 22 – June 26 2026
The 2026 OSTST meeting will take place in Wiesbaden, Germany, from 22 to 26 June 2026.
The yearly Ocean Surface Topography Science Team meeting includes plenary sessions, the splinter working sessions, and poster sessions.
Once again in 2026, satellite altimetry experts from around the world will gather to discuss the performance of current satellite altimetry constellations as well as the use and information-sharing about all present, past, and future altimeter missions.
The meeting will cover the main applications of satellite altimetry related to open oceans, coastal areas, polar regions, cryosphere, and inland waters.
The meeting is open to international experts and global users of satellite altimeter data from all missions (Jason-3, Sentinel-3, Sentinel-6, CryoSat-2, SARAL/AltiKa, SWOT, HY-2, etc.) and those working on future altimetry missions.
In addition, since the successful launch of the Copernicus Sentinel-6B satellite in November 2025, this OSTST meeting will place a strong focus on the commissioning status and activities of this mission with a dedicated Sentinel-6 Validation Team splinter, where teams will report on the findings from the satellite’s commissioning. And once again, this OSTST edition will be combined with a meeting of the International DORIS Service.
The abstract submission period is open from January 19th until April 3rd on this page. Please log in and use the menu bar “Manage abstract/New abstract” to submit.
