Abstract

In 2005, research studies to define, develop and validate SAR Ocean Wind, Waves and Currents level 2 products prototypes were initiated and supported by ESA. The first phase of this project ended in December 2006 with the development of two prototypes allowing respectively the generation of SAR Level2 wind and waves products duly validated. A set of clear recommendations were also made in particular for the next European SAR Sentinel-1 mission.

This project entered into its second phase in 2007 during which, ENVISAT ASAR L2 wind wand waves prototypes will be produced over the European waters and a number of 4 specific sites (super-sites). Level-2 products will be generated over a 2-year period in order to achieve several objectives: long term validation over a large range of oceanic and atmospheric situations, demonstration of realistic Level-3 products. Last but not least, this will help potential users (met offices, offshore, harbour authorities, coastal management, civil engineering, ship routing operators ...) to get accustomed and to have the possibility to assess the usefulness of these new SAR wind/wave products. Level-2 wind and wave maps will be available on the Web in Near Real time

The processing chain from satellite acquisition to results dissemination will be presented here, together with scientific/technical achievements and preview of the web interface.
