Light use efficiency model is one of the parametric models for estimating vegetation productivity based on remote sensing data. Its core parameter, maximum light use efficiency ( LUEmax ), was considered as a fixed value in the early stage (e.g., CASA). Moreover, it had become a parameter varying with vegetation types since MODIS-LUE model (MOD17), and recently it was considered to be dynamic with the phenology and physiological status of vegetation.
Although current vegetation productivity estimation models based on seasonally dynamic LUEmax has showed a relatively higher accuracy, their studies were still limited in fewer vegetation types or smaller scales. Therefore, the applicability of different dynamic LUEmax are not very clear in wider areas.
We assessed three typical dynamic simulation methods of LUEmax (which based on Chlorophyll Index, Leaf Area Index and Markov Chain Monte Carlo) by using the same dataset (FLUXNET 2015) and model structure (MODIS-LUE).
