摘要

Although the emissivity behavior of soil moisture has been the subject of numerous research works, making a critical survey of published results, it is possible to find some inconsistencies. The works establish that the effect of increasing soil moisture is principally reduce reflectance and increase emissivity. However, using the direct method for measurement of emissivity, different results were obtained. A dozen of different kinds of soil from the region were analyzed, at different moisture levels and it was found that in all of them, as the moisture content increases, emissivity of the sample decreases.
