Data underlying the publication: Plant–atmosphere heat exchange during wind machine operation for frost protection

<strong>***General Introduction***</strong>This dataset contains data collected during the Clarity on Fruitfrost project at Delft University of Technology, as part of J. Boekee's PhD Thesis project.It is being made public both to act as supplementary data for publications of J. Boekee and in order for other researchers to use this data in their own work.The data in this data set was collected in Krabbendijke, The Netherlands, on 13-14 April 2021 and 7-8 May 2021.This research project was made possible by a grant from the NWO.<strong>***Purpose of the measurement campaign***</strong>The purpose of these experiments was to study frost protection by a wind machine in a fruit orchard.<strong>***Description of the data in this data set***</strong>The data included in this data set has been organised per instrument. The files follow the nomenclature system: Month_instrument_loc with loc = wind direction + number of tree rows distance to the wind machineThe precise location of the instruments is mapped in a google earth file: data_location_4TU_May.kmz and data_location_4TU_April.kmz. In April following instruments are included: radiometer, DTS, weather stations, soil temperature sensors. In May additional sonic-anemometers and plant thermocouples are included.<br>

**一、项目概述**
本数据集收录了代尔夫特理工大学（Delft University of Technology）开展的Clarity on Fruitfrost项目期间采集的数据，该项目是J. Boekee博士论文研究的组成部分。本次数据集公开发布，既可作为J. Boekee相关学术成果的补充数据，也可供其他科研人员在其研究工作中使用。本次数据集的采集地点为荷兰克拉本迪克（Krabbendijke），采集时间为2021年4月13日至14日，以及2021年5月7日至8日。本研究项目得益于荷兰科学研究组织（Nederlandse Organisatie voor Wetenschappelijk Onderzoek, NWO）的经费资助。

**二、测量试验的目的**
本次试验的核心目标为研究果园内风机的霜冻防控效果。

**三、数据集内容说明**
本数据集收录的数据已按采集仪器进行分类整理。数据文件遵循统一命名规则：`月份_仪器名称_位置标识`，其中位置标识（loc）由风向参数与至风机的果树行数间距共同组成。仪器的精确位置已在谷歌地球（Google Earth）文件`data_location_4TU_May.kmz`与`data_location_4TU_April.kmz`中标注。2021年4月的观测数据包含以下仪器的采集结果：辐射计（radiometer）、分布式温度传感器（Distributed Temperature Sensor, DTS）、气象站、土壤温度传感器。2021年5月的观测数据额外新增了超声风速仪（sonic-anemometer）与植物热电偶（plant thermocouple）的观测结果。
