Hourly estimates of sap flow during the snow-free seasons of 2010-2012 for trees growing at the terrace, forest and treeline sites in Alaska

Hourly estimates of sap flow during the snow-free seasons of 2010-2012 for trees growing at the terrace, forest and treeline sites. Units are L dm-2 sapwood area hr-1. Measurements were made using Dynamax thermal dissipation probes (TDP 30). Probes were installed such that the heater was at a depth of 2.5 cm and the thermocouples were 1.0 cm beneath the bark.

本数据集涵盖2010至2012年无雪季期间，生长于台地、森林及林线样地的树木的树干液流（sap flow）逐小时估算值。其单位为升/(平方分米·边材面积·小时)。所有测量均采用Dynamax热消散探针（Thermal Dissipation Probe，TDP 30）完成。探针安装方式为：加热元件埋设于皮下2.5厘米深度处，热电偶则位于皮下1.0厘米深度处。
