Description:Snow cover over the Tibetan Plateau (TP) plays an important role in Asian climate. State ‐of‐ the‐art models, however, show signi ficant simulation biases. In this study, we assess the main uncertainty associated with model physics in snow cover modeling over the TP using ground ‐based observations and high ‐resolution snow cover satellite products from the Moderate Resolution Imaging Spectroradiometer (MODIS) and FengYun ‐3B (FY3B). We first conducted 10 ‐km simulations using the Noah with multiparameterization (Noah ‐MP) land surface model by optimizing physics ‐scheme options, which reduces 8.2% absolute bias of annual snow cover fraction (SCF) compared with the default model settings.
