Dendrometer data at The Morton Arboretum Forestry Plots 2019-2023

We are collecting long-term dendrometer data at The Morton Arboretum to determine seasonal growth patterns in trees. This data on stem growth patterns will eventually be integrated with other ongoing data streams to paint a broader picture of plant phenology. This data package contains the outputs from three types of dendrometer devices: ICT band dendrometer data is in the "ICT_data2020_2023.csv" file, TreeHugger band dendrometer data is in the "TreeHugger_data2019_2020.csv" file, and TOMST point dendrometer data is in the "TOMST_data2021_2023.csv" file. The TreeHugger and TOMST files contain corrected and raw uncorrected values, whereas the ICT data file contains only raw data. Initial tree size data at device installation is located in the "Initial_Tree_Size.csv" file. Additional information on units are contained within each data file's respective data dictionary, and the location metadata file contains the geographic locations of the 23 forestry plots at The Morton Arboretum as well as the measured tree species at each location.

本研究于莫顿树木园（The Morton Arboretum）收集长期树木径向生长仪（dendrometer）数据，以解析树木的季节生长模式。这批针对茎干生长模式的数据集最终将与其他同步采集的数据流整合，全面勾勒植物物候的整体图景。本数据包包含三类树木径向生长仪设备的输出结果：ICT带状径向生长仪数据存储于"ICT_data2020_2023.csv"文件，TreeHugger带状径向生长仪数据存储于"TreeHugger_data2019_2020.csv"文件，TOMST点状径向生长仪数据存储于"TOMST_data2021_2023.csv"文件。TreeHugger与TOMST文件同时包含校正后与原始未校正数据，而ICT数据文件仅包含原始数据。设备安装时记录的初始树木尺寸数据存储于"Initial_Tree_Size.csv"文件中。各数据文件的配套数据字典中包含单位相关补充信息；位置元数据文件则记录了莫顿树木园内23个林地样地的地理位置，以及各样地内实测的树木物种信息。
