Abstract :
Oceanic internal waves were observed by microwave radiometers from a blimp during the COPE´99 experiment. Brightness temperature variations caused by sea surface roughness modulation and enhanced wave breaking were compared with model calculations. It is shown that direct wave amplitude modulation by currents cannot explain the observed brightness temperature variations, but inclusion of wave breaking and foam coverage modulation results in a good agreement with experimental data.
