2009-2020年全球1km、5天植被总初级生产力净初级生产力产品

数据集包括2009-2020年全球1km、5天的植被总初级生产力和净初级生产力产品。总初级生产力（GPP）为绿色植物在单位时间单位面积上由光合作用产生的有机物质总量；净初级生产力（NPP）为总初级生产力（GPP）中扣除自养呼吸后的剩余部分。产品包括GPP、GPP_QC、NPP、NPP_QC共4个波段。该产品使用全球风云3号（FY-3A/3B）卫星数据，针对42种自然植被类型的构建区分植被气候带的反演模型，最后得到不同植被类型的GPP和NPP。

This dataset includes global 1-kilometer, 5-day vegetation Gross Primary Productivity (GPP) and Net Primary Productivity (NPP) products spanning 2009 to 2020. Gross Primary Productivity (GPP) refers to the total amount of organic matter produced by green plants via photosynthesis per unit time and per unit area; Net Primary Productivity (NPP) is the residual portion of GPP after subtracting autotrophic respiration. The product contains four bands: GPP, GPP_QC, NPP, and NPP_QC. This product utilizes global Fengyun-3 (FY-3A/3B) satellite data, constructed inversion models that differentiate vegetation climate zones for 42 natural vegetation types, and finally derives GPP and NPP values for different vegetation types.
