Google Earth Engine ——MOD17A3HGF.006: Terra Net Primary Production Gap-Filled Yearly Global 500m

The MOD17A3HGF V6 product provides information about annual Net Primary Productivity (NPP) at 500m pixel resolution. Annual NPP is derived from the sum of all 8-day Net Photosynthesis (PSN) products (MOD17A2H) from the given year. The PSN value is the difference of the Gross Primary Productivity (GPP) and the Maintenance Respiration (MR) (GPP-MR).

MOD17A3HGF V6产品提供500米像素分辨率的年度净初级生产力（NPP）信息。年度净初级生产力是由给定年份的所有8天净光合作用（PSN）产品（MOD17A2H）之和得出的。PSN值是总初级生产力（GPP）和维持呼吸（MR）之差（GPP-MR）。
