The SOPRANO demonstration product consists of a grid of SAR wave spectra extracted from a subset of a full SAR image. It also contains significant wave height and dominant wavelength and direction for the three most energetic wave partitions detected in each SAR wave spectrum.
The spacing of the wave spectra grid is typically 5km and the SAR wave spectra has the same structure (including number of wavenumber and direction bins) as the GlobWave SAR L2P product.
Error characterisation of the SOPRANO wave product is done by extracting retrieved swell information in the SOPRANO wave product over reference buoys when images are acquired over one of the reference buoys. Significant wave height, dominant wavelength and directional error statistics are then be estimated by comparing swell partitions from the SOPRANO product to spectral partitioning of the in situ wave spectra.
Soprano is available at the following web site where further details and instructions for its use can be found:
