Tumbarumba Flux Data Collection

This dataset consists of measurements of the exchange of energy and mass between the surface and the atmospheric boundary-layer in wet sclerophyll forest using eddy covariance techniques.
The Tumbarumba flux station is located in the Bago State Forest in south eastern New South Wales. It was established in 2000 and is managed by CSIRO Marine and Atmospheric Research. The forest is classified as wet sclerophyll, the dominant species is Eucalyptus delegatensis, and average tree height is 40m. Elevation of the site is 1200m and mean annual precipitation is 1000mm. The Bago and Maragle State Forests are adjacent to the south west slopes of southern New South Wales and the 48,400 ha of native forest have been managed for wood production for over 100 years. The instrument mast is 70m tall. Fluxes of heat, water vapour and carbon dioxide are measured using the open-path eddy flux technique. Supplementary measurements above the canopy include temperature, humidity, wind speed, wind direction, rainfall, incoming and reflected shortwave radiation and net radiation. Profiles of temperature, humidity and CO2 are measured at seven levels within the canopy. Soil moisture content is measured using Time Domain reflectometry, while soil heat fluxes and temperature are also measured. Hyper-spectral radiometric measurements are being used to determine canopy leaf-level properties. The Tumbarumba flux station is supported by TERN and the DCCEE through the ACCSP.

本数据集采用涡度协方差（eddy covariance）技术，采集了硬叶湿润林（wet sclerophyll forest）地表与大气边界层之间的能量与物质交换观测数据。
Tumbarumba通量站（Tumbarumba flux station）坐落于新南威尔士州东南部的巴戈州立森林（Bago State Forest），该站点于2000年建成，由澳大利亚联邦科学与工业研究组织（CSIRO）海洋与大气研究所负责运维。该林区属于硬叶湿润林，优势树种为高山桉（Eucalyptus delegatensis），平均树高40米，场地海拔1200米，年平均降水量达1000毫米。巴戈与马雷格尔州立森林毗邻新南威尔士州南部西南坡，这片总面积48400公顷的原生林已有超过百年的木材生产经营历史。
观测塔高70米，研究人员采用开路式涡度通量（open-path eddy flux）技术观测热通量、水汽通量与二氧化碳通量。冠层上方的补充观测项目包括空气温度、空气湿度、风速、风向、降雨量、入射短波辐射、反射短波辐射以及净辐射。研究人员在冠层内7个高度层上开展气温、湿度与二氧化碳浓度的垂直廓线观测。土壤含水率采用时域反射仪（Time Domain Reflectometry, TDR）进行测定，同时同步观测土壤热通量与土壤温度。研究团队还采用高光谱辐射测量技术，获取冠层叶片尺度的生理生态特征参数。
Tumbarumba通量站由陆地生态系统研究网络（TERN）、澳大利亚气候变化与能源效率部（DCCEE）通过澳大利亚气候变化科学计划（ACCSP）提供支持。如需获取更多站点详情，请访问：https://www.tern.org.au/tern-observatory/tern-ecosystem-processes/tumbarumba-wet-eucalypt-supersite/。该数据集亦可通过http://data.ozflux.org.au 获取。
