Groundwater level elevation and temperature across Meander C at the Lower Montane in the East River Watershed, Colorado.

This groundwater level elevation and temperature data package is aimed at improving the predictive understanding of hydro-biogeochemical processes at the lower montane site in the East River Watershed, Colorado. The dataset is obtained using pressure transducers placed in shallow wells in the floodplain. This dataset contains data from wells ER-CPA1 to ER-CPA6 (six wells with SFA Location ID's). Each file contains the water level elevation and the water temperature. Water level elevation have been obtained using the barometric pressure from the pressure transducer (Hobos sensor) in the well, barometric pressure from a sensor in air located at the same site (lower montane), depth from top-of-casing (TOC) to sensor measurement point, and TOC elevation. Data have been checked with a few measurements of water table depths. A real-time kinematic (RTK) global positioning system (GPS) has been used to survey the TOC (data in file WellLocation_WLdataArchive2018). The water level elevation is given in UTM13N Geoid2012AB. While depth to water level is not present in the data files, it can be easily calculated with the TOC and distance to ground provided in the GPS coordinate file (WellLocation_WLdataArchive2018). The dataset quality is discussed in Collection/Analysis section of the methods. Time-series of measurements will be added to this data package, so please check back for updates. If you have questions, please contact the author.

本地下水水位高程与温度数据集包，旨在提升对科罗拉多州东河流域下游山地站点水文生物地球化学过程的预测认知。本数据集通过安置于漫滩浅井内的压力传感器采集获得，涵盖ER-CPA1至ER-CPA6共6口带有SFA位置标识的监测井的数据。每个数据文件均包含水位高程与水温数据。水位高程的计算依据包括：监测井内压力传感器（Hobos传感器）测得的气压、同一下山地站点的空气气压传感器数据、套管顶部（top-of-casing, TOC）至传感器测量点的深度，以及套管顶部高程。数据集已通过少量地下水位深度实测数据进行了校核。已采用实时动态（Real-time Kinematic, RTK）全球定位系统（Global Positioning System, GPS）对套管顶部高程进行勘测，相关数据存储于WellLocation_WLdataArchive2018文件中。水位高程采用UTM13N Geoid2012AB坐标系表示。尽管数据文件中未包含地下水位埋深数据，但可结合GPS坐标文件（WellLocation_WLdataArchive2018）中提供的套管顶部高程与地面距离参数，快速计算得到地下水位埋深。数据集的质量详情可参见研究方法中的采集/分析章节。本数据集后续将补充时序监测数据，请持续关注更新。如有任何疑问，请联系数据集作者。
