英文摘要	Roughness height for heat transfer is a crucial parameter in the estimation of sensible heat flux. In this study, the performance of the Surface Energy Balance System (SEBS) has been tested and evaluated for typical land surfaces on the Tibetan Plateau on the basis of time series of observations at four sites with bare soil, sparse canopy, dense canopy, and snow surface, respectively. Both under-and overestimation at low and high sensible heat fluxes by SEBS was discovered. Through sensitivity analyses, it was identified that these biases are related to the SEBS parameterization of bare soil's excess resistance to heat transfer (kB(-1), where k is the von Karman constant and B-1 is the Stanton number). The kB(-1) of bare soil in SEBS was replaced. The results show that the revised model performs better than the original model.
