研究表明，被动微波遥感可以反演土壤湿度信息。 如果植被的影响得到校正，甚至在存在植被冠层时也是可能的。 植被校正算法必须尝试包括所有重要的物理参数，但它们也必须只需要可以容易地获得的数据。 以前的研究提出了一个模型，试图满足这些要求。 这个模型的关键是估计的植被参数B的特点冠层。 在这项研究中，我们评估了已发表的数据，以确定该参数对植被特征的功能依赖。
Research has shown that soil moisture information can be retrieved by passive microwave remote sensing. This is even possible when there is a vegetation canopy present if the effects of the vegetation are corrected for. Vegetation correction algorithms must attempt to include all significant physical parameters, yet they must also only require data that can be readily obtained. Previous research proposed a model that attempted to meet these requirements. Critical to this model is the estimation of a vegetation parameter b that characterizes the canopy. In this study we evaluated published data to determine the functional dependence of this parameter on vegetation characteristics.
