应用核驱动BRDF模型与AVHRR数据监测撒哈拉土壤表面动态变化(英文)

The Application of Kernel-driven BRDF Models and AVHRR Data to Monitoring Land Surface Dynamics in the Sahel

将要用来处理来自即将开始运行的ＥＯＳＭＯＤＩＳ和ＭＩＳＲ仪器的ＢＲＤＦ／反照率乘积的反照率反演程序包中的ＢＲＤＦ模型在该文中被用来对来自ＡＶＨＲＲ数据的ＳＡＨＥＬ地区的方向反射数据进行建模。模型被证明能够很好地描述观测到的数据。同时也讨论了核的选择和导出模型的参数所含的信息内容等问题。

The Ambrals BRDF model which will be used to process the BRDF/Albedo product from data from the forthcoming EOS MODIS and MISR instruments is used to model directional reflectance data of the Sahel from AVHRR data. The model proves to be capable of describing the observed data well. Issues related to kernel selection and information content of the derived model parameters are addressed.
