Welcome to the International Coastal Altimetry Community
In the last few years, considerable research has been carried out into extending the capabilities of current and future altimeters as close as possible to the coast, with the ultimate aim to integrate the altimeter-derived measurements of sea level, wind speed and significant wave height into coastal ocean observing systems. At the same time the major Space Agencies have recognized the importance of coastal altimetry and are sustaining coastal altimetry research through dedicated projects. This new coastal altimetry community, inherently interdisciplinary, has already had ten well-attended international workshops (see below and http://www.coastalaltimetry.org), and has produced a book on the subject, plus a Community White Paper for the OceanObs'09 conference.
DATASETS FOR COASTAL ALTIMETRY (table updated Jul 2019)
Our mailing list: COASTALT-SWT
The Coastal Altimetry Science Working Team (COASTALT-SWT) is an informal grouping of scientists around a mailing list [coastalt-swt] for quick and efficient exchange of information, results and news on Coastal Altimetry.
The list is hosted on the NOC server and has more than 200 international contacts. It is the most effective way of reaching out to the coastal altimetry community.
COASTALT-SWT reports informally to the Ocean Surface Topography Science Team, which we see a bit like our 'parent' group.
TO JOIN COASTAL-SWT OR POST AN ITEM:
The mailing list is moderated by Chris Banks at NOC so please contact Chris if you are interested in joining the mailing list. To post an item, send the message to Chris.

10th Coastal Altimetry Workshop - Florence, Italy, 21-24 February 2017 – Programme – Extensive summary of the Workshop – Brief summary for AGU EOS. Presentations will be online soon
This included sessions on studies using the new Jason-3 and Sentinel-3 data, and special sessions jointly with the Altimetry for Regional and Coastal Models (ARCOM) community of GODAE COSS-TT, and the Sea Level community and data providers. The workshop was accompanied by a SAR Altimetry Training Course for the benefit of early career scientists and any satellite oceanographer who would like to get more familiar with the SAR mode on CryoSat-2 and Sentinel-3.
