冠层水平阵列湍流研究（CHATS）于2007年春季进行，是水平阵列湍流研究（HATS）系列实验中的第三个。HATS实验在行星边界层（PBL）湍流大涡模拟（LES）的子过滤尺度（SFS）模型的测试和开发中发挥了重要作用。CHATS活动在加州的狄克逊附近的一个落叶核桃果园进行，旨在研究植被对SFS湍流的影响。测量收集之前和之后的叶子，以捕捉叶片上的湍流，分层，和标量源/汇分布的影响。CHATS利用快速响应的仪器阵列来研究动量提取和标量源对SFS动量，能量和三个标量传输的树冠施加的分布的影响。为了直接测试和链接到PBL参数化的冠层修改的湍流交换，CHATS还包括一个30米的剖面。
The Canopy Horizontal Array Turbulence Study (CHATS) took place in spring 2007 and is the third in the series of Horizontal Array Turbulence Study (HATS) experiments. The HATS experiments have been instrumental in testing and developing subfilterscale (SFS) models for large-eddy simulation (LES) of planetary boundary layer (PBL) turbulence. The CHATS campaign took place in a deciduous walnut orchard near Dixon, California, and was designed to examine the impacts of vegetation on SFS turbulence. Measurements were collected both prior to and following leafout to capture the impact of leaves on the turbulence, stratification, and scalar source/sink distribution. CHATS utilized crosswind arrays of fast-response instrumentation to investigate the impact of the canopy-imposed distribution of momentum extraction and scalar sources on SFS transport of momentum, energy, and three scalars. To directly test and link with PBL parameterizations of canopy-modified turbulent exchange, CHATS also included a 30-m profile ...
