Envisat ASAR WM Ocean Wave Spectra L2 [ASA_WVW_2P]
Listed in NASA Earthdata CMR
Description
This ASAR Wave Mode product is created by inverting the cross-spectra which is computed from inter-look processing of the SLC wave imagettes in order to derive the directional ocean product ocean wave spectra. Auxiliary ADSs included with the product remains the same as for the ASAR Wave Mode Cross-Spectra product (_$$ASA_WVS_1P$$ earth.esa.int/eogateway/catalog/envisat-asar-wave-imagette-cross-spectra-l1-asa_wvs_p- ).
The output follows the format of the Envisat ASAR Level 1B Wave Mode Cross-Spectra Imagette (_$$ASA_WVS_1P$$ earth.esa.int/eogateway/catalog/envisat-asar-wave-imagette-cross-spectra-l1-asa_wvs_p- ) 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.

The ASAR Wave products were processed operationally using the version of PF-ASAR available at the time of processing and are available in Envisat format. Output: Wavelength range from 20 to 1000 m in 24 logarithmic steps.
