Google Earth Engine ——非洲净初级生产量（NPP）数据集FAO/WAPOR/2/L1_NPP_D

Net primary production (NPP) is a fundamental characteristic of an ecosystem, expressing the conversion of carbon dioxide into biomass driven by photosynthesis. The pixel value represents the mean daily NPP for that specific dekad.

净初级生产量（NPP）是生态系统的一个基本特征，表示在光合作用的驱动下将二氧化碳转化为生物量。像素值代表该特定德卡德的平均每日净初级生产力。
