Plant canopy reflectance models developed by Suits are tested for cotton and Penjamo winter wheat. Properties of the models are discussed, and the concept of model depth is developed. The models' predicted exchange symmetry for specular irradiance with respect to sun polar angle and observer polar angle agreed with field data for cotton and wheat. Model calculations and experimental data for wheat reflectance vs sun angle disagreed. Specular reflectance from 0.50micro to 1.10 microm shows fair agreement between the model and wheat measurements. An Appendix includes the physical and optical parameters for wheat necessary to apply Suits' models.
对苏茨开发的植物冠层反射率模型进行了棉花和彭贾莫冬小麦的测试。讨论了模型的特性，并提出了模型深度的概念。模型预测的镜面辐照度相对于太阳极角和观测者极角的交换对称性与棉花和小麦的田间数据相符。小麦反射率与太阳角度的模型计算结果与实验数据不一致。0.50微米至1.10微米的镜面反射率显示模型与小麦测量结果之间有较好的一致性。附录包括应用苏茨模型所需的小麦物理和光学参数。
