摘要 针对近年兴起的适用于大范围区域平均通量观测的大孔径闪烁仪(LAS),建立了一个基于欧拉分析方法的LAS印痕模型,用于对LAS测量数据的印痕分析和质量控制。作者介绍模式的建立方法并对模式的输入参数进行了讨论。另外,应用LAS印痕模式来分析2005年小汤山非均匀下垫面的观测实验数据,并与涡动相关数据进行线性回归分析,获得较好的相关性。结果显示该LAS印痕模型在观测数据的分析中有很大的实用价值,适用于非均匀下垫面的研究。 The large aperture scintillometer (LAS) is a versatile instrument to measure area-average heat fluxes over heterogeneous surface. In order to analyze the source area of LAS data, a new Eulerian analytical footprint model is developed. The parameters of the LAS footprint are discussed in detail and some outcome of the model, application over a heterogeneous field experiment are shown. The good agreement of the results demonstrates that this footprint model is an effective and practical tool for complex surface study.
