Paper Abstract

In some arid and semi-arid high-altitude mountainous area of the western China, snowmelt water is the most important water resources and snowmelt water supply amount to river is even more than 75%, but there will be flood if the snowmelt water cause spring flood. So it is necessary to comprehend the large-scale snowmelt status. This study describes a snowmelt model based on a physical heat balance method. Using Terra remote sensing data of EOS/MODIS which cover Xinjiang province at midday to inverse some parameters of the model, incorporating meteorological data to get the instantaneous heat balance information, then to calculate daily melt water based on study of B.Sequin, B.ltier and Xianqiong Xie. It improves snowmelt model algorithms. In addition, we use MODIS remote sensing data to monitor snow cover, avoiding the improper estimation to free-snow area.
