Town Hall 1: Operational monitoring of global and regional sea level by satellite altimetry
Over the last 26 years, sea level has been measured by a host of satellite mission, launched and operated by the various space agencies world wide. Together they clearly identify not only the approximately 3 mm/year rise in global mean sea level, but also the regional deviations from the global mean. The monitoring has mainly relied on the reference altimeter missions (TOPEX and the Jason family of satellites), but recent efforts like ESA's Sea Level Climate Change Initiative have brought other missions to meet the same high standards required for sea level change monitoring. In addition, fiducial measurement campaigns have been set up to cross-calibrate the satellite systems with in-situ tide gauges. In this session the various space agencies will present their involvement and commitment to ensure the continuation of the sea level climate data record from satellite altimetry into the future and the upkeep of the older data with improved knowledge of altimeter data corrections, orbit determination, etc. The moderator and speakers invite the conference participants to share their expectations and possible needs for improvement of current and future services and products delivered by the agencies.

Town Hall 2: Meeting evolving requirements of integrated sea level observations for regional and local decision making
The 2006 Sea Level Conference provided a comprehensive statement on requirements for Sea Level information and recommendations on sustaining satellite and in situ observations and developing observing system capabilities.
Over 10 years on, the need for information at the regional and local level is more critical, and more complex, requiring for instance the synthesis of Sea Level information with the likelihood of extreme weather events. As technology and analysis methods evolve, how do we extract maximum benefit from the combination of satellite and in situ observing systems? Can we improve the integration of Sea Level, geodetic and hydro-meteorological data to deliver information fit for meeting regional/local decision-making requirements?
