Fractional Cover - Bare Soil (2012-03-05)

Data are MODIS NBAR-derived 16-days fractional cover of Photosynthetic Vegetation (PV), Non-Photosynthetic Vegetation (NPV) and Bare Soil (BS). Fractional cover represents the exposed proportion of PV, NPV or BS within each pixel. In forested canopies the photosynthetic or non-photosynthetic portions of trees may obscure those of the grass layer and/or bare soil.

本数据集包含基于中分辨率成像光谱仪（MODIS）天底双向反射分布函数校正反射率（NBAR）反演得到的16天合成光合植被 PV (Photosynthetic Vegetation)、非光合植被 NPV (Non-Photosynthetic Vegetation) 与裸土 BS (Bare Soil) 覆盖度数据。覆盖度指单个像素内光合植被、非光合植被或裸土的暴露占比。在森林冠层中，树木的光合或非光合部分可能会遮蔽草本层及/或裸土的对应区域。
