Reproducibility of hydrological process by LSM in semi-arid grassland on seasonal frost

Abstract

The aim of this study is to investigate the reproducibility of hydrological processes by Land surface model (LSM) in semiarid grassland on seasonal frost. The validation of MATSIRO was carried out over the grassland on seasonal frost sites at Tongyu in China and Kherlen Bayan Ulaan in Mongolia. Two kinds of experiments have been carried out, which LSM was run with the default parameters (CTL) and observed parameters (OBS) for soil physics and hydrology, and vegetation. The OBS run showed better reproducibility than CTL run especially for soil temperature while soil moisture showed poor reproducibility for both.
