Abstract
The purpose of this paper is to validate the BEPS model in crops for net primary productivity (NPP) estimation and to study the spatial scaling effects of NPP using both airborne and field data. The results show that the highest differences between modeled NPP at resolution 15 m and 30 m are greater than those re-sampled from modeled NPP at 3 m resolution, especially at the boundary of winter wheat.
