| Zusammenfassung |
| We scrutinized the surface energy partitioning on the Tibetan Plateau through comparative
analysis of the two biosphere models (i.e., Simple Biosphere Model version 2 and Noah LSM
version 2.7) constrained by the in-situ observation data. Our extensive analysis shows that
the different behaviors of the two land surface models mainly resulted from the
differences in (1) the parameterization for soil evaporation, (2) the way to deal with
roughness lengths of momentum and scalars, and (3) the parameterization of sub-grid
velocity scale for turbulent exchange coefficients. Unique environments on the Tibetan
Plateau provide useful information for the improvement in simulating surface energy
partitioning using biosphere models. Our study further suggests that one should carefully
interpret the model results on the Plateau especially during pre-monsoon period. |
