Abstract
In this paper, we focus on winter wheat yield assessment in Hebei province in china. The method take two procedures: first, we extract phenological transition dates from MODIS-LAI. Then, using SCE_UA algorithm, we assimilated the phenology information into crop growth model SWAP. The results shown that an improved accuracy of crop yield can be achieved compared to the method with no assimilation algorithm.
