Soil Pit Sensor Data, Volumetric Water Content and Temperature, Far North Queensland Rainforest SuperSite, Daintree Rainforest Observatory, Cape Tribulation, 2011

A soil pit was dug to 1.5 m depth in July 2007 and monitoring probes were installed at 0.1, 0.75 and 1.5 m depths in three columns. At each depth there were 3 time domain reflectometry probes (Campbell Scientific CS616) to measure volumetric water content, 3 gypsum blocks (Measurement Engineering Australia GBHeavy, except at 0.1 m depth were there were only 2) to measure water potential over the range -30 to -600 kPa. In addition one TCAV thermocouple probe to record soil temperature was located in the centre of the soil pit at 0.10m. In each column the time domain reflectometry and gypsum blocks were separated laterally by 20cm, each column was separated from the next by 100cm. At each depth the time domain reflectometry and gypsum blocks were separated laterally by 1 m.

2007年7月挖掘了一处深度达1.5米的土坑，并在三根测柱的0.1、0.75和1.5米深度处安装监测探头。各深度处均布设3支时域反射仪（time domain reflectometry）探头（Campbell Scientific CS616型号），用于测定土壤体积含水量；另有3块石膏块传感器（Measurement Engineering Australia GBHeavy型号，仅在0.1米深度处安装2块），可在-30至-600 kPa量程内测定土壤水势。此外，在土坑中心的0.10米深度处安装1支TCAV型热电偶探头，用于记录土壤温度。每根测柱内的时域反射仪探头与石膏块传感器横向间距为20厘米，相邻测柱之间的间距为100厘米；同一深度处的时域反射仪探头与石膏块传感器横向间距为1米。
