本文介绍了天山山脉碎屑覆盖的冰川的消融测量结果。这些测量被用来根据碎屑层的厚度得出覆盖有碎屑的冰的度日系数。其次，根据卫星图像观测到的表面温度计算碎片层厚度。厚度计算采用了三种类型的拟合函数，并对冰上湖泊、冰崖和正常冰川碎屑覆盖的冰川区域进行了区分。计算出的碎屑厚度和碎屑厚度
In this paper the authors present ablation measurements on a debris-covered glacier in the Tien Shan mountain range. These measurements are used to derive degree day factors for debris covered ice, depending on the thickness of the debris layer. Secondly the debris layer thickness is calculated from surface temperatures observed with a satellite image. The thickness calculations are done with three types of fitting functions and, in addition, a distinction is made for supra glacial lakes, ice cliffs and ’normal’ debris covered glacier area. The combination of the calculated debris thickness and
