Outline of Final Research Achievements |
The purpose of this study is to find the clue for improving the reproducibility of hydrological processes by land surface model in semi-arid climate in Mongolia. The simulation by the land surface model (original and improved versions for the frozen soil process of MATSIRO) has been done over the semiarid grassland sites in Mongolia. The reproducibility of the net radiation, the soil temperature, and latent heat flux were well reproduced by the experiment with the observed soil parameters. The change of soil physical and hydraulic parameter affected the reproducibility of and soil moisture as well as energy flux component especially for the sensible heat flux and soil heat flux, which is likely to include the ice effect on the soil heat capacity and the thermal conductivity. In seasonal frozen ground such as grassland in Mongolia, the importance of soil parameter and frozen soil process on the reproducibility of energy and water budget was found.
