Abstract

Light use efficiency model is one of the method to retrieval regional scale Gross Prime Productivity (GPP). Absorbed Photosynthetic Active Radiation (APAR) and Light use efficiency are the main parameters of this kind of model. At the same time, light use efficiency is affected by air temperature and precipitation. In this article, one of the Light use efficiency model is used to retrieval daily GPP of the Chinese five typical ecosystem experimental station in 2003. The inversion results are compared with MOIDS NPP product and station measurement data. Based on the different air temperature and precipitation condition of the different station, it also analyses the sensitivity of parameters.
