Riggs Creek Flux Data Collection

This dataset consists of measurements of the exchange of energy and mass between the surface and the atmospheric boundary-layer in a pastoral area using eddy covariance techniques.The flux station site is located within an area of dryland agriculture. The surrounding area is dominated by broadacre farming practices. The vegetation cover is predominantly pasture. Elevation of the site is close to 152m and mean annual precipitation at a nearby Bureau of Meteorology site measures 650mm. Maximum temperatures range from 12.3°C (in July) to 29.7°C (in February), while minimum temperatures range from 10.4°C (in July) to 26.8°C (in February).The instrument mast is 4 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 and net radiation are measured. Soil heat fluxes are measured and soil moisture content is gathered using time domain reflectometry.This data is also available at http://data.ozflux.org.au .本数据集采用涡度协方差（eddy covariance）技术，采集了某牧区地表与大气边界层间的能量与物质交换观测数据。该通量观测站坐落于旱地农业区内，周边区域以大规模大田耕作模式为主，区域植被以牧草为主。站点海拔约152米，附近澳大利亚气象局（Bureau of Meteorology）观测站点记录的年平均降水量为650毫米。月最高气温介于12.3℃（7月）至29.7℃（2月）之间，月最低气温介于10.4℃（7月）至26.8℃（2月）之间。观测塔杆高度为4米。采用开路式涡度通量技术开展热通量、水汽通量与二氧化碳通量的观测；同步测量气温、湿度、风速、风向、降雨量与净辐射。土壤热通量通过直接观测获取，土壤含水率则采用时域反射仪（time domain reflectometry）进行采集。该数据集亦可通过 http://data.ozflux.org.au 下载获取。
