    Abstract

    Envisat/ASAR-derived offshore wind speeds and energy densities based on 4 different SAR wind speed retrieval algorithms (CMOD4, CMOD-IFR2, CMOD5, CMOD5.N) are compared with observed wind speeds and energy densities for evaluating offshore wind energy resources. CMOD4 ignores effects of atmospheric stability, while CMOD5.N assumes a neutral condition. By utilizing Monin-Obukov similarity theory in the inverse LKB code, equivalent neutral wind speeds derived from CMOD5.N are converted to stability dependent wind speeds (CMOD5N_ SDW). Results of comparison in terms of energy density indicate the CMOD5N_SDW shows the lowest errors than the other algorithms.
