Abstract

ENVISAT ASAR wave mode products have been monitored and validated continuously against corresponding ECMWF wave model counterparts since the early stage of ENVISAT life. Recent status of the wave mode products will be presented. Furthermore, the rather long-term timeseries of the differences with respect to the ECMWF wave model will be displayed and discussed.

ERS-2 SAR wave mode product has been assimilated operationally at ECMWF wave model since January 2003. The impact of SAR assimilation will be displayed. ENVISAT ASAR wave mode level 1b product will replace ERS-2 in the next version of the operational model expected to be operational early 2006. Results from the numerical experiments verifying the usefulness of this change will be presented.
