Summary of the Workshop:

6th Coastal Altimetry Workshop
Riva del Garda, Italy
20-21 September 2012

The scientific community involved in the research and development of applications of satellite altimetry in the coastal zone met for the 6th Coastal Altimetry Workshop. Research in coastal altimetry is going through exciting times: experimental datasets for the coastal zone are now available, such as those from the French PISTACH project for the Jason-2 satellite and from the European Space Agency (ESA)-funded COASTALT project for the Envisat satellite, and many diverse applications were shown at the workshop. These range from observing coastal currents to monitoring river and lake levels, ice margins, and storm surges to gravity mapping in coastal zones.

It was apparent from the workshop that there has been a gear shift in the analysis of echoes in the coastal zone, in the geophysical corrections (several new correction techniques having been proposed in the past few years for the wet tropospheric delay), and in the integration of coastal altimetry in the observing and forecasting systems. Synthetic aperture radar (SAR) (delay-Doppler) altimetry, on board Cryosat-2 and planned for the operational Global Monitoring for Environment and Security mission Sentinel-3, is now revolutionizing the field, and many talks dealt with applying this new technique, exploiting the amplitude and phase of the very high repeat frequency radar echoes.

There are still challenges to the processing, such as waveform building and retracking and correction of the sea state bias, but the quality of the data that are being produced by ESA, the French National Centre for Space Studies (CNES), and the U.S. National Oceanic and Atmospheric Administration is extremely promising, and initiatives like ESA’s SAR Altimetry Mode Studies and Applications (SAMOSA) study on the improvement in precision with respect to conventional altimetry have confirmed that the choice of a SAR altimeter for Sentinel-3 is a good one. Other challenges are the integration with models—on which there were several talks and posters—and the ever-crucial need for the calibration and validation of the reprocessed data. Future missions, such as AltiKa and 2D altimeters, were also illustrated.

The workshop issued some recommendations . Noteworthy is the request to use an interleaved mode, using both pulse-limited and SAR, over the entire globe for the planned Jason-CS mission, and to maximize the use of SAR acquisition area over the oceans for the Sentinel-3 mission.

The Coastal Altimetry Workshop, with 88 participants from 25 countries, 32 talks, and 24 posters, was a strong, lively, passionate community review of science and applications that continued the success of previous editions and confirmed that coastal altimetry is truly emerging as the new frontier of altimetry. These messages were fully taken up by the wider altimetry community gathered in Venice for the “20 Years of Progress in Radar Altimetry” symposium, Argo Workshop, and Ocean Surface Topography Science Team (OSTST) meeting the following week, where coastal altimetry had a dedicated session, a dedicated keynote talk in the opening plenary session, a workshop report in the OSTST splinters’ session, and a good amount of mention in the roundtable on future observational requirements.
