Ivey Soil Monitoring Sensor Data

This dataset contains data from the Ivey Pecan Orchard soil monitoring sensor array. These sensors are installed at two sites with contrasting soil textures - Pecan_Fine and Pecan_Coarse. At each of these sites, there are the following sensors: VWC, EC, T, O2, CO2 at 30cm and 60cm depths, and CO2 efflux at the soil-air interface. At Pecan_Coarse, there is also a differential pressure sensor measuring the difference between ambient pressure and soil pressure, in order to better capture changes in pressure. These changes in pressure may contribute to changes in CO2 efflux as advection dominates over diffusive CO2 transport.

本数据集收录了艾维山核桃园（Ivey Pecan Orchard）土壤监测传感器阵列的实测数据。该传感器阵列部署于两个土壤质地迥异的监测点位：Pecan_Fine与Pecan_Coarse。每个监测点位均部署了以下传感器：埋设深度为30cm与60cm的体积含水量（Volumetric Water Content，缩写VWC）、电导率（Electrical Conductivity，缩写EC）、土壤温度（Temperature，缩写T）、氧气浓度（Oxygen，缩写O2）与二氧化碳浓度（Carbon Dioxide，缩写CO2）传感器，以及土壤-空气界面处的二氧化碳外排通量传感器。在Pecan_Coarse点位，还额外部署了差压传感器，用于监测环境气压与土壤气压的差值，以更精准地捕捉气压变化。当平流输送在二氧化碳运移过程中占据主导地位时，此类气压变化可能会引发二氧化碳外排通量的改变。
