Gross primary productivity (GPP) and Net primary productivity (NPP) are key components of the terrestrial carbon cycle. In this paper, an improved light utilization efficiency model was used to estimate GPP and NPP in East China from 2001 to 2008. This model included two sub models: GPP model and respiration model. The data input into the model including remote sensing data: MODIS production such...
