利用痕迹模拟方法对青藏高原两处地方涡度方差的测量数据进行了质量分析,揭示了其空间和时间结构.分析表明高达1/3的测量没有达到必要的数据正确假设.尽管这样对潜热、CO2、动量通量的测量基本通过测试,可以适用于基础研究,但是经常发现特定的风矢量违背基本假设条件.感热通量的测量允许使用不间断的连续测量法,然而由于局地地形的影响少量评估指数未能合理解释,但能够指示出组织结构及用于导出边界层中尺度流体模型假说.“,”A quality analysis including footprint modelling has revealed spatial and temporal structures in the quality of Eddy Covariance measurements for two highland sites located on the Tibetan plateau. Fetch analysis has shown, that up to 1/3 of the measurements do not fulfill assumptions necessary for a physically correct data processing. Despite this fact, measurements of latent heat-, CO2-and momentum flux in general fulfill the quality test criteria to an extend that the results can be regarded as suitable for fundamental research, whereby usually certain wind sectors have been found violating basic assumptions. Measurements of the sensible heat flux allow for the usage in continuously running measurement, while still few indications of the quality assessment can not be explained due to local topography, but indicate organized structures and lead to the hypothesis of mesoscale flow patterns in the boundary layer.
