Data and codes for Vertical flux divergence comparison between two-height eddy-covariance observations and large-eddy simulations in Enschede, The Netherlands

This dataset contains the observational and modeling data used in the study of vertical sensible heat flux divergence above an urban rooftop in Enschede, the Netherlands. It includes two-height eddy-covariance observations, near-surface meteorological variables, and large-eddy simulation outputs for two contrasting case studies: a windy shear-dominated event and a calm buoyancy-dominated event. This collection contains the codes and dataset for reproducing the figures in the manuscript, illustrating the observational setup, simulation domain, model evaluation, sensible heat flux divergence, flow structure, flux–gradient relationships, vertical profiles, and double-averaged statistics. The figures support the analysis of how local flow distortion and non-local turbulent transport govern rooftop flux divergence under contrasting atmospheric conditions.本数据集收录了荷兰恩斯赫德市一处城市屋顶上方垂直感热通量散度研究中所用的观测与模拟数据，涵盖两项对比性案例研究的相关数据类型：两层高度的涡动协方差（eddy-covariance）观测结果、近地面气象变量数据，以及大涡模拟（large-eddy simulation）输出结果。两项案例分别为强风剪切主导事件与静稳浮力主导事件。 本配套资源包含用于复现论文手稿中各类图表的代码与数据集，图表内容涵盖观测设置、模拟域、模型评估、感热通量散度、流场结构、通量-梯度关系、垂直廓线以及双重平均统计量。上述图表可支撑相关分析，用以阐明在不同大气条件下，局地流场畸变与非局地湍流输运如何调控屋顶上方的通量散度。
