Slope variance obtaining from buoy data and validation by TOPEX/Poseidon measurements

摘要

The method to obtain large-scale, in comparison with the probing wavelength, sea waves slope variance from buoy measurements is proposed. The idea is to use integration of sea spectrum which parameters can be fully determined by buoy measurements in case of pure wind sea and mixed sea containing fully developed wind waves and swell. The algorithm is validated and corrected by TOPEX altimeter data collocated with buoy measurements.
