冬季积雪(BTS)底部温度的测量构成了绘制冬季地面结冰和山区永久冻土条件图的可靠方法。除了有关BTS的信息外，微型温度记录仪还提供雪盖持续时间、零幕期长度、融水渗透开始、年平均地表温度、地面冻结和融化持续时间等信息。它们使人们能够更好地了解复杂的高高山活动层过程。相应的测量结果很好地适用于检验永久冻土分布模式PERMEBAL中实施的积雪模块。第一个结果表明，测量温度之间的主要差异是由调查地点的高度变化的地表特征造成的，积雪积累的时间对于解释BTS测量非常重要。这些结果提供了关于山区标准化长期观测的可能性和局限性以及将其应用于监测和建模的信息。2003年7月斯威茨和泽特林格，利塞，ISBN 90 5809 582 7 8月10月12月3月5月6月7月时间
Measurements of Bottom Temperatures of the winter Snow cover (BTS) constitute a wellestablished method to map ground freezing in winter and, hence, permafrost conditions in mountain areas. Besides information on BTS, miniature temperature loggers also provide information about, snow-cover duration, length of zero-curtain periods, onset of meltwater percolation, mean annual ground-surface temperatures, duration of ground freezing and thawing, etc. They enable a better insight into the complex high-alpine active-layer processes. Corresponding measurements are well-suited to test the snow-cover module implemented in the permafrost distribution model PERMEBAL. First results show that the main differences between the measured temperatures are caused by highly variable surface characteristics at the investigated sites and that the timing of the snow cover accumulation is very important for the interpretation of the BTS-measurements. These results provide information about possibilities and limitations of standardized long-term observations in mountain areas and their application to monitoring and modelling.
