Adelaide River OzFlux tower site

Ecosystem flux data from the Adelaide River site, Northern Territory.

The Adelaide River flux station was located approximately 10.5km south east of Bachelor, Northern Territory: 13?04'37.2?S, 131?7'4.8"E.

The flux tower site was classified as Savanna dominated by Eucalyptus tectifica and Planchonia careya.

Elevation of the site was close to 90m and mean annual precipitation at a nearby Bureau of Meteorology site is 1730mm. Maximum temperatures range from 31.4?C (in June) to 36.8?C (in October) while minimum temperatures range from 16.2?C (in July) to 25.1?C (in December). Maximum temperature vary seasonally by approximately 5.4?C and minimum temperatures vary by approximately 8.9?C.

The instrument mast was 15 meters tall. Heat, water vapour and carbon dioxide measurements were taken using the open-path eddy flux technique. Temperature, humidity, wind speed, wind direction, rainfall, incoming and reflected shortwave radiation and net radiation were measured above the canopy. Soil heat fluxes are measured and soil moisture content was gathered using time domain reflectometry.

北领地阿德莱德河站点生态系统通量数据集。

阿德莱德河通量观测站坐落于北领地巴彻勒（Bachelor）东南方向约10.5公里处，地理坐标为南纬13°04'37.2''、东经131°07'04.8''。

该通量塔站点为以Eucalyptus tectifica与Planchonia careya为优势物种的稀树草原（Savanna）生态系统。

站点海拔接近90米，邻近的澳大利亚气象局（Bureau of Meteorology）站点记录的年平均降水量为1730毫米。气温季节波动特征显著：最高气温介于31.4℃（6月）至36.8℃（10月）之间，最低气温介于16.2℃（7月）至25.1℃（12月）之间；最高气温季节变幅约5.4℃，最低气温季节变幅约8.9℃。

观测桅杆高度为15米。研究采用开路径涡度通量法（open-path eddy flux technique）对热量、水汽与二氧化碳通量进行观测。冠层上方同步测量了气温、相对湿度、风速、风向、降雨量、入射与反射短波辐射及净辐射。土壤热通量与土壤含水量均开展了观测，其中土壤含水量采用时域反射仪（time domain reflectometry）进行采集。
