The "25 years of Progress in Radar Altimetry" Symposium will take place from Monday 24 to Saturday 29 September 2018, in Ponta Delgada, São Miguel Island, Azores Archipelago (Portugal).

Following on from the "15 Years of Progress in Radar Altimetry"  Symposium in 2006 and the "20 Years of Progress in Radar Altimetry"  Symposium in 2012, in Venice-Lido, Italy, both deemed very successful landmarks by the participants and the readership of the Proceedings, we are now at the twenty-five year anniversary of the launch of ERS-1 and TOPEX/POSEIDON. To mark this occasion the  European Space Agency, in collaboration with the French Space Agency,  CNES, is organising an exceptional Symposium on "25 Years of Progress in Radar Altimetry". This event will also be sponsored by other partner agencies and organisations supporting the development of altimetry. Along with this symposium, several related events will take place on the same week, including the annual meeting of the Ocean Surface Topography Science Team (OSTST) and the International Doris Service (IDS) workshop, as well as other thematic workshops still to be organised; potential topics are Sea Level for Climate, Coastal Zone, Space for Hydrology, Argo, etc. These events will be held over 6 days, from 24 to 29 of September 2018, in Ponta Delgada, São Miguel Island, Azores Archipelago (Portugal). 

Please consider your participation at this exceptional event and reserve the week from 24 to 29 September 2018 in your agenda. For the symposium, a call for papers with detailed information and deadlines will be sent subsequently, along with the details of a dedicated web site to submit your contributions to be reviewed by the Scientific Committee. For OSTST and IDS meetings, additional information and call for contributions will be sent out and linked to the same website.
    

Looking forward to another great "slow-time" event like the 15 and 20 Years of Progress in Radar Altimetry held in Venice in 2006 and 2012, an exceptional scientific Symposium on "25  Years  of  Progress  in  Radar  Altimetry"!
