| 内容記述 | Radiometric measurements of vegetation have been conducted by placing reflecting metal screens under three types of vegetation, and using a radiometer operating in the 11.1 and 5.88 cm wavelengths. A theoretical model involving a loss term and a scattering albedo value was fitted to the measured temperatures. Canopy absorption and scattering must be determined to assess the vegetation's effect on microwave sensor sensitivity to the dielectric properties of the underlying soil. Using the theoretical model and calculated absorption and scattering values derived from the screened fields, the effect of vegetation cover on soil emission was predicted. A comparison of predicted full canopy temperatures with those measured was then conducted. |
