    This data product is created by inverting the cross-spectra computed from inter-look processing of the SLC imagettes to derive the directional ocean product ocean wave spectra. Auxiliary ADSs included with the product remains the same as for the Cross-Spectra product.

    The output follows the format of the Envisat ASAR Level 1B Wave Mode Imagette Cross-Spectra (ASA_WVS_1P) product. This is done in order to be compatible with the ground segment products of Envisat ASAR.

    This product provides a continuation of the ERS-SAR wave mode data.

    Output: Wavelength range from 20 to 1000 m in 24 logarithmic steps
