Google Earth Engine ——MOD17A2H V6总初级生产力（GPP）产品是一个具有500米分辨率的8天累积综合数据产品

The MOD17A2H V6 Gross Primary Productivity (GPP) product is a cumulative 8-day composite with a 500m resolution. The product is based on the radiation-use efficiency concept and can be potentially used as inputs to data models to calculate terrestrial energy, carbon, water cycle processes, and biogeochemistry of vegetation.
