Abstract
<p>Water use in Central Asia highly depends on meltwater of glaciers. In order to know the meltwater’s seasonal availability, seasonal change of glacial water/heat balance should be clarified. This research aims to demonstrate SWE’s behavior on a land-surface process model SiBUC, which requires 7 meteorological factors for input data, using observed data and re-analysis data JRA55 as the input data. Since the sensor failed to observe snowfall, snowfall amount was reproduced by using observed snow depth and estimated density. SWE calculation was done in two ways; by using observed data (with reproduced precipitation), and by replacing each factor with JRA55, which aims to see the discrepancy between JRA55 and observed data and how it leads to the error in SWE. The result showed that the accuracy of short wave and long wave radiation particularly in the snowmelt season is crucial to the correct demonstration of SWE.</p>
