抽象。冰川质量平衡模型依赖于对输入数据，特别是气温进行精确的空间计算。与环境条件相比，冰川通常会出现较低的温度（所谓的冰川冷却效应）和较低的温度变化（所谓的冰川阻尼效应）。这些影响取决于冰川的几何特征，并显示出很高的空间和时间变化性，迄今为止，大多数研究都集中在中型至大型冰川上，而对较小冰块的观测（
Abstract. Glacier mass balance models rely on accurate spatial calculation of input data, in particular air temperature. Lower temperatures (the so-called glacier cooling effect) and lower temperature variability (the so-called glacier damping effect) generally occur over glaciers compared to ambient conditions. These effects, which depend on the geometric characteristics of glaciers and display a high spatial and temporal variability, have been mostly investigated on medium to large glaciers so far, while observations on smaller ice bodies (
