Soil- moisture and temperature from the PhytOakmeter plot FFOL_13 (Fontain, France) from 2021@en

As part of PhytOakmeter (www.phytoakmeter.de), time-domain transmission, soil moisture and -temperature sensors with custom-made logger systems were used to measure time series of soil state variables. The aim of these investigations was to provide data on environmental properties used in a cross-disciplinary approach.The measurement device consisted of two sensors at three different depths. The dataset contains the values of time (UTC), relative permittivity, soil moisture (in % vol) derived from permittivity and soil temperature (in °C). Determination of soil moisture was done using the formula of Topp et al. (1980). As sensors, the SMT100 soil moisture sensors with integrated temperature measurement were used. All sensors were installed within the upper 50cm below ground. The exact depths for each sensor are listed in the dataset and parameter comment.作为PhytOakmeter（www.phytoakmeter.de）项目的一部分，本研究采用搭载定制化记录系统的时域传输型土壤水分与土壤温度传感器，采集土壤状态变量的时间序列数据。本研究的目标是为跨学科研究提供所需的环境属性相关数据。该测量装置在三个不同深度各部署两枚传感器。本数据集包含以下参数的数值：协调世界时（UTC）时间、相对介电常数、由介电常数推导得到的体积含水率（单位：% vol）以及土壤温度（单位：°C）。土壤含水率的计算采用Topp等人于1980年提出的公式。本次研究使用的传感器为集成温度测量功能的SMT100型土壤水分传感器。所有传感器均布设于地下50厘米以浅的土层范围内。各传感器的具体埋设深度已在数据集及参数注释中列明。
