| Summary: | The document is the eighth and final technical report of the series. It summarizes six years of basic and applied research into the microwave emission characteristics of natural materials and the environment. Research activities encompass investigations of the ocean and coastal environment, snowpack and ice studies, sediment and soil studies, dielectric constant measurements and techniques, and analytical modeling of natural materials and the environment. Field studies were conducted with a mobile microwave field laboratory containing a number of microwave radiometers and supporting instrumentation. Oceanographic research has been concerned with the effects of microwave emission of ocean surface roughness, water temperature, salinity, and surface pollutants. Hydrologic studies were concerned with the physics of microwave emission by snowpacks, fresh and sea ice. Other investigations have been concerned with the emission characteristics of sediments and soils and the determination of soil moisture content with microwave radiometry. The report also provides a detailed account of the current year's research which entails multiwavelength microwave radiometric measurements and numerical modeling of controlled, small scale waves.
