| dc.description.abstract | This study used a vertically integrated hydrological and meteorological real-time monitoring system to observe the air-temperature, wind speed and direction, air-pressure, relative humidity, precipitation, pan-evaporation, net radiation, solar radiation, soil temperature and soil moisture at the NCU meteorological site. We used those meteorological data and in situ soil characteristics to run the SHAW model and discussed the results of mass and thermal fluxes of land processes at this site.
With the given initial conditions (soil temperature and water content) and the hourly weather conditions (air-temperature, wind speed, relative humidity), the SHAW model can simulate diurnal variations of soil moisture and temperature. During rainfall periods, the saturation of soil moisture can be simulated by the model as a result of infiltration. For the recession period of soil moisture, after rainfalls cease, the discrepancies between simulated and observed soil moistures are getting larger along with the increase of simulation time.
The long-term trend of most soil temperature can be fairly described by the model, but the simulated surface temperature is higher than observed data at midday. | en_US |
