Soil Environmental Conditions in the East River Watershed, CO

This dataset contains depth-resolved soil environmental variables collected between June 2016 and October 2018 from the Bradley Meadow site in the East River watershed. Datalogger output from 7 Campbell CS655 12 cm Soil Moisture and Temperature Sensors including depth, temperature, volumetric water content, and electrical conductivity are included in ‘BM_Merged_T_VWC_0616_10_18.csv’. Sensors were installed in June 2016. Data have been processed to merge raw sensor data and to remove additional variables. No additional QA/QC was performed. Measured pCO2 and depth are contained in ‘BM_EGM_WELL_CO2.csv’. These data represent gas well samples measured via injection using a PP Systems EGM-5 infra-red gas analyzer as described in the methods section. Measured CO2 surface flux values are contained in 'BM_EGM_Surface_Flux.csv'. These were measured using the PP Systems EGM-5 with the Soil Respiration Chamber attachment. Multiple reps are reported for each measurement including CO2 flux rate calculations using built-in linear and quadratic function methods, and average and standard deviations are taken across all reps and calculation methods.

本数据集收录了2016年6月至2018年10月期间，于东河流域（East River watershed）布拉德利草甸（Bradley Meadow）站点采集的深度解析型土壤环境变量数据。'BM_Merged_T_VWC_0616_10_18.csv'中包含7台坎贝尔（Campbell）CS655型12厘米土壤水分与温度传感器的日志输出数据，涵盖深度、温度、体积含水量及电导率四项指标。该批传感器于2016年6月完成安装。已对数据进行预处理，合并原始传感器采集数据并剔除冗余变量，未开展额外的质量控制与质量保证（QA/QC）工作。'BM_EGM_WELL_CO2.csv'收录了实测二氧化碳分压（pCO₂）与深度数据，此类数据为气井样本，采用PP Systems EGM-5型红外气体分析仪通过注入法完成测量，具体方法详见研究方法章节。'BM_EGM_Surface_Flux.csv'收录了实测CO₂地表通量值，测量采用搭载土壤呼吸室附件的PP Systems EGM-5型红外气体分析仪完成。每次测量均设置多个重复样本，测量过程中内置线性与二次函数法用于计算CO₂通量速率，最终取所有重复样本及所有计算方法的平均值与标准差作为最终结果。
