Temperature data used for waterfall plots

General description of the temperature data used in the paper: There are seven data files containing the three-dimensional data sets (temperature against distance and time) captured by the Halo DTS analyser manufactured by Sensornet Ltd. File names are: 0am_20150401.csv; 0am_20150503.csv; 12am_20150504.csv; 0am_20150529.csv; 23pm_20150612.csv; 0am_20150614.csv In each file the y axis is time, and the name of each file indicates the starting time and date (i.e. 0am, 20150401; 0am, 20150503; 12am, 20150504; 0am, 20150529; 23pm, 20150612; 0am, 20150614). The total measurement time for each file is 24 hours. The time interval between each data point is 2 minutes. The x axis is distance, starting from 0 m at the location of the DTS analyser. The total distance in each file is 1218m. The distance interval between each data point is 2.03m. The temperature unit is degree Celsius, time interval: 2 minutes, distance interval: 2.03m.本文所用温度数据的总体说明如下： 本数据集共包含7个数据文件，存储由Sensornet有限公司生产的Halo型分布式温度传感（Distributed Temperature Sensing，DTS）分析仪采集得到的三维数据集，即温度随距离与时间的变化数据。 数据文件名称依次为：0am_20150401.csv、0am_20150503.csv、12am_20150504.csv、0am_20150529.csv、23pm_20150612.csv、0am_20150614.csv。 各文件的纵轴代表时间，文件名本身即标注了数据的起始时刻与日期（如0am_20150401对应0时、2015年4月1日）。单个文件的总测量时长为24小时，数据点间的时间间隔为2分钟。 横轴代表距离，以DTS分析仪的安装位置为零点（0米）。每个文件的总测量距离为1218米，数据点间的距离间隔为2.03米。 温度单位为摄氏度，数据采集的时间间隔为2分钟，距离间隔为2.03米。
