2009-2020年全国30m植被总初级生产力逐旬产品

数据集包括2009-2020年中国30m的植被总初级生产力和净初级生产力逐旬产品。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。产品包括GPP、GPP_QC共2个波段。产品数据源为高分一号宽幅相机（GF-1-WFV）和环境（HJ-1 CCD）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 contains 30-meter resolution ten-day composite products of vegetation gross primary productivity (GPP) and net primary productivity (NPP) across China from 2009 to 2020. Gross primary productivity (GPP) refers to the total amount of organic matter produced via photosynthesis by green plants per unit time and per unit area. The product includes two bands: GPP and GPP_QC. The data sources of this product are Gaofen-1 Wide Field of View (GF-1-WFV) and Huanjing-1 CCD (HJ-1 CCD) satellite imagery. An inversion model that distinguishes vegetation climate zones was constructed for 42 types of natural vegetation, and finally GPP and NPP products for different vegetation types were derived.
