Whiffle LES runs over 8x8 km^2 by 5.2 km domain around Cabauw, The Netherlands.

In our study we looked at the mixing impact on wind and momentum fluxes in relation to the cloud conditions overhead. We used both LES and observations in a nine-year long time-series, which is unique for LES. The following LES output files are provided between 2009 -- 2017:<br>Large Eddy Simulations for researching wind mixing at Cabauw run with GPU Resident Atmospheric Simulation Platform (GRASP) developed by Whiffle. For each year of simualtions, the four files are available: <br>1. Meteo values of at the location of the Cabauw tower<br>2. Domain and hourly averaged profiles of, among others, temperature, wind, humidity and their fluxes.<br>3. Slices of the integrated liquid water path for every 10 min4. Conditionally sampled average profiles for: <br> - updraughts (w&gt;0) <br> - cloudy updraughts (w&gt;0 and ql &gt;0 ) - cloud (ql&gt;0) - cloud core (w&gt;0, ql &gt;0 and th_v' &gt; 0)<br>

本研究围绕高空云况对风场与动量通量混合过程的影响展开分析。本研究采用大涡模拟（Large Eddy Simulation, LES）与观测数据构建了九年时长的时间序列，该数据集针对大涡模拟研究而言具有独特性。本数据集提供2009年至2017年间的大涡模拟输出文件：<br>用于研究卡堡（Cabauw）地区风场混合过程的大涡模拟，由Whiffle公司开发的GPU驻留大气模拟平台（GPU Resident Atmospheric Simulation Platform, GRASP）运行生成。针对每一年的模拟结果，均提供以下四类文件：<br>1. 卡堡观测塔测点的气象要素值<br>2. 模拟域逐小时平均廓线，涵盖温度、风场、湿度及其通量等要素<br>3. 每10分钟输出的积分液态水路径切片数据<br>4. 条件采样平均廓线，具体类别如下：<br> - 上升气流（垂直速度w>0）<br> - 含云上升气流（w>0且比湿ql>0）<br> - 云区（ql>0）<br> - 云核区（w>0、ql>0且虚位温扰动th_v'>0）
