摘要 生物物理特性的遥感通常依赖于仅使用在红色和近红外通道中获取的数据，这些数据通常结合在植被指数中，例如归一化植被指数（NDVI）。这浪费了从其他渠道获取的信息，并且可能妨碍生物物理特性的准确估计。利用基于红光和近红外辐射的植被指数来估计热带森林的生物物理特性收效甚微，这可能是由于指数与生物物理特性之间关系的渐近性质、不同环境下植被指数对植被生物物理特性的敏感度不同、红光和近红外通道反射的辐射较低以及大气水和气溶胶的严重衰减所致。对于热带森林，估计区域到全球范围内的生物物理特性的唯一可行方法是通过使用国家海洋和大气数据...
Abstract The remote sensing of biophysical properties has generally relied on the use of data acquired in red and near-infrared channels only, often combined in a vegetation index such as the Normalized Difference Vegetation Index (NDVI). This is wasteful of information acquired in other channels and may prevent the accurate estimation of biophysical properties. The use of vegetation indices based on red and near-infrared radiation to estimate biophysical properties of tropical forests has met with little success and this may be due to the asymptotic nature of the relation between the indices and biophysical properties, the variable sensitivity of vegetation indices to vegetation biophysical properties in different environments, the low radiation reflected in red and near-infrared channels, and severe attenuation by atmospheric water and aerosols. For tropical forests the only feasible way to estimate biophysical properties at regional to global scales is through the use of the National Oceanic and Atmosp...
