Digby Plantation Flux Data Release 2024_v2

This release consists of flux tower measurements of the exchange of energy and mass between the surface and the atmospheric boundary-layer using eddy covariance techniques. Data were processed using PyFluxPro (v3.4.17) as described by Isaac et al. (2017). PyFluxPro produces a final, gap-filled product with Net Ecosystem Exchange (NEE) partitioned into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER).

The Digby Plantation flux station was installed in a recently planted blue gum (Eucalyptus globulus) plantation near the town of Digby in western Victoria, Australia. The plantatiopn was establlished in August 2017 with a tree density of approximately 1000 trees per hectare. The seedlings were about 30 cm tall and the trees were about 11 m tall in July 2021. The equipment was installed on an extendable tower that was moved from 5 m at the beginning of the monitoring period to about 15 m at the end of the experiment, following the growth of the trees.

本数据集包含采用涡度协方差（eddy covariance）技术获取的地表与大气边界层间能量、物质交换通量塔观测数据。数据依据Isaac等人（2017年）的方法流程，使用PyFluxPro（v3.4.17）完成处理。PyFluxPro可生成经过间隙填充的最终数据集，将生态系统净交换（Net Ecosystem Exchange, NEE）划分为总初级生产力（Gross Primary Productivity, GPP）与生态系统呼吸（Ecosystem Respiration, ER）。

Digby人工林通量站设于澳大利亚维多利亚州西部Digby镇周边的新近营造蓝桉（Eucalyptus globulus）人工林内。该人工林于2017年8月建成，初始造林密度约为1000株/公顷。2021年7月时，初始定植的幼苗株高仅约30厘米，而同期林木平均高度已达约11米。观测设备安装于可伸缩塔架之上，随林木生长进程，塔架高度从监测初期的5米逐步调整至试验末期的约15米。
