Validation of hydrological process by LSM and observation in semi-arid grassland

Abstract

To investigate the reproducibility of hydrological process by land surface process model MATSIRO in semi-arid grassland in China and Mongolia. The soil temperature (Ts) was well reproduced by model. Although the freezing phase had good agreement between observation and model, the simulated Ts started earlier thawing than the observation. The soil moisture was not well reproduced by the model. In winter time the reproducibility of soil moisture become worst when soil was frozen. There was good agreement between the model and observation for the latent heat flux and net radiation while it was poor for sensible heat flux.
