Daly Uncleared OzFlux tower site

The Daly River Uncleared flux tower site is located in the Douglas River Daly River Esplanade Conservation area, approximately 60 km south west of Pine Creek, Northern Territory: 14?09'33.12"S, 131?23'17.16"E (-14.1592,131.3881).

The flux tower site is classified as a Woodland savanna. The overstory is co dominated by tree species E. tetrodonta, C. latifolia, Terminalia grandiflora Sorghum sp. and Heteropogon triticeus. Average canopy height measures 16.4 m. Elevation of the site is close to 110m and mean annual precipitation at a nearby Bureau of Meteorology site is 1170mm.

Maximum temperatures range from 37.5?C (in October) to 31.2?C (in June), while minimum temperatures range from 12.6?C (in July) to 23.8?C (in January). Maximum temperatures range seasonally by 6.3?C and minimum temperatures by 11.2?C.

The instrument mast is 23 meters tall. Heat, water vapour and carbon dioxide measurements are taken using the open-path eddy flux technique. Temperature, humidity, wind speed, wind direction, rainfall, incoming and reflected shortwave radiation and net radiation are measured above the canopy.

Ancillary measurements taken at the site include LAI, leaf-scale physiological properties (gas exchange, leaf isotope ratios, N and chlorophyll concentrations), vegetation optical properties and soil physical properties. Airborne based remote sensing (Lidar and hyperspectral measurements) was carried out across the transect in September 2008

戴利河未清理通量塔站点（Daly River Uncleared flux tower site）坐落于道格拉斯河-戴利河滨岸保护区（Douglas River Daly River Esplanade Conservation Area）内，北领地派恩克里克西南约60公里处，地理坐标为南纬14°09'33.12''、东经131°23'17.16''（十进制坐标为-14.1592, 131.3881）。
该通量塔站点被归类为稀树草原林地（Woodland savanna）。林冠层由四蕊桉（E. tetrodonta）、C. latifolia、大花榄仁（Terminalia grandiflora）、高粱属（Sorghum sp.）以及长柄异芒草（Heteropogon triticeus）共同构成优势群落，林冠平均高度为16.4米。站点海拔接近110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1170毫米。
极端最高气温区间为37.5℃（10月）至31.2℃（6月），极端最低气温区间为12.6℃（7月）至23.8℃（1月）。最高气温季节波动幅度为6.3℃，最低气温季节波动幅度为11.2℃。
观测塔架高度为23米。热通量、水汽通量与二氧化碳通量采用开路涡度相关法（open-path eddy flux technique）进行观测。林冠上方同步测定气温、相对湿度、风速、风向、降雨量、入射与反射短波辐射以及净辐射。
站点配套观测项目包括叶面积指数（LAI）、叶片尺度生理特性（气体交换、叶片同位素比值、氮素与叶绿素浓度）、植被光学特性以及土壤物理特性。2008年9月，研究团队沿样带开展了机载遥感观测，涵盖激光雷达（Lidar）与高光谱测量。
