ISLSCP II Global Primary Production Data Initiative Gridded NPP Data

Net Primary Production (NPP) is an important component of the carbon cycle and, among the pools and fluxes that make up the cycle, it is one of the steps that are most accessible to field measurement. Direct measurement of NPP is not practical for large areas and so models are generally used to study the carbon cycle at a global scale. This data set contains 2 *.zip files for above ground and total NPP data.

净初级生产力（Net Primary Production，简称NPP）是碳循环中的关键组成部分，在构成循环的各个库和通量中，它是最易于现场测量的步骤之一。对于大面积区域的NPP的直接测量并不切实际，因此通常使用模型来研究全球尺度的碳循环。本数据集包含2个*.zip文件，分别用于存储地上和总NPP数据。
