Abstract : For quite sometime oceanographers and meteorologists have been attempting to describe dynamic ocean features as a function of various meteorological parameters. Data used in past studies have been limited by location, instrumentation, and processing. Only recently have remote sensing techniques been applied to determining dynamic ocean features. The results of recent passive and active microwave experiments are presented in the papers contained in this report. Passive microwave (radiometric) observations appear to show that this technique may be capable of determining surface roughness conditions (sea state, spray, percentage of foam and whitecaps, etc.). Active microwave (radar) results appear to show a non-linear relationship of the backscatter cross section as a function of windspeed. Radar data is also being used to describe more fully the high frequency component of the ocean wave spectrum. (Author)
