Abstract

ENVISAT Fast Delivery ASAR Wave Mode products are routinely received, monitored and validated at ECMWF. ASAR Wave Mode Level 1b (ASA_WVS_1P) product is inverted using the MPIM scheme to obtain the ocean wave spectra. This product agrees well with the wave model counterpart in terms of all used integrated parameters. This product has been assimilated operationally at ECMWF since 1 February 2006.

On the other hand, ASAR Wave Mode Level 2 Ocean Wave Spectrum (ASA_WVW_2P) product agrees well with the wave model in terms of swell significant wave height and mean period. The agreement is not so good for the other parameters describing the spectral shape.

The latest status of this ongoing work will be presented.
