The net primary productivity (NPP) of vegetation reflects the efficiency of plant to fix and transform light energy into compounds. It refers to the amount of organic matter accumulated by green plants in unit time and unit area. It is the total amount of organic matter produced by plant photosynthesis (gross primary productivity, GPP) minus autotrophic respiration n. The remainder after RA), also known as net primary productivity. NPP, as an important part of surface carbon cycle, not only directly reflects the production capacity of vegetation community in the natural environment, but also an important part of measuring regional land use / cover change. The net primary productivity data product is a kind of multi-scale grid data product which is retrieved from a variety of satellite remote sensing data (Landsat, MODIS, etc.) by using the glow model algorithm. This data is also the main factor to determine and adjust the ecological process.
