Vertical tree air temperature measurements within the canopy of the HJ Andrews Experimental Forest, 2011-2019

Vertical air temperature from 11 trees in the Andrews Forest has been collecting beginning in 2011. The trees are at a variety of elevations and are of various species and ages. The 11 trees were selected form the H.J Andrews phenology study air temperature network (MS045). This study examines air temperatures at multiple heights in each tree. The first sensor is at 1.5 m and subsequent sensors measure every 5 m up the tree. Each sensor includes a light (illumination) sensor, which can be used to assess the value of the data. This is not a measurement of the actual light conditions.

本数据集自2011年起开始采集安德鲁兹森林（Andrews Forest）内11棵树木的垂直气温数据。这些树木分布于不同海拔高度，且涵盖不同树种与树龄。本次选取的11棵树木均来自H.J.安德鲁兹物候学研究气温监测网络（MS045）。本研究针对每棵树木的多个高度层级开展气温监测：首个传感器安装于1.5米高度，后续传感器沿树干每间隔5米布设一个。每个气温传感器均配套搭载光照（illumination）传感器，可用于辅助评估数据的有效性，但该传感器并非用于实测真实光照环境。
