Goals are to provide measurements of short-scale sea surface roughness in the shoaling wave zone, determine the correlation between this short-scale slope variance and surface wind stress, and finally suggest the ramifications to microwave remote sensing in the shoaling zone. Primary objective is to determine the characteristics of near-vertical incidence millimeter-wave radar backscatter in the surf zone and out to sea. This information relates directly to an integration of the sea surface spectrum over wave scales from 1 m down to 1 cm. The short-scale waves are known to be well-coupled to the wind stress. Technical objective will be to obtain collocated wind stress, long wave, and absolutely calibrated near-vertical radar scattering data together over the shoaling zone.
