Paint Rock Environmental Data (AIMS_SE_PRF_ENVI)

This resource includes static environmental data collected for the sensor and sampling locations in the Paint Rock research watershed (outlet location: 34.96861724, -86.16501705) on privately owned property in Jackson County (AL, USA) as part of the Aquatic Intermittency effects on Microbiomes in Streams (AIMS) project, an NSF EPSCoR funded project (OIA 2019603). The project sought to explore the impacts of stream drying on downstream water quality across Kansas, Oklahoma, Alabama, and Idaho, integrating datasets on hydrology, microbiomes, macroinvertebrates, and biogeochemistry. The watershed drains a non-perennial unnamed tributary to Burks Creek, and contains 2.97 km^2 of deciduous forest in the Cumberland Plateau physiographic section. Located near Estillfork, AL, the watershed spans an elevation range from 211 to 550 m above sea level, and is a tributary to the Paint Rock River (within the larger Tennessee basin). The region has a humid subtropical climate, with mean daily January and July air temperatures of 4.4°C and 25.4°C respectively, and mean annual precipitation of 1,390 mm/yr. All data was extracted from Digital Elevation Model (DEM) rasters provided by the USGS National Map Downloader v2.0. Additionally, accompanying watershed_PRF.zip and streamnetwork_PRF.zip files contain .shp files containing the watershed boundary polygon and delineated stream network lines respectively. The watershed was delineated to the outlet location (site: PRM01), and the stream network was delineated using a threshold of 60,000 cells to most closely match the field-observed geomorphic stream network.本数据集包含为佩恩特罗克（Paint Rock）研究流域内传感器与采样点位采集的静态环境数据，该流域出口点位坐标为34.96861724, -86.16501705，坐落于美国阿拉巴马州杰克逊县境内的私有土地之上，隶属于“溪流微生物组的水文间歇性影响（Aquatic Intermittency effects on Microbiomes in Streams, AIMS）”项目——这是一项由美国国家科学基金会（NSF）EPSCoR计划资助的项目（项目编号：OIA 2019603）。 该项目旨在探究溪流干涸对堪萨斯州、俄克拉荷马州、阿拉巴马州以及爱达荷州下游水质的影响，整合了水文、微生物组、大型无脊椎动物以及生物地球化学相关数据集。 该流域为伯克溪（Burks Creek）一条无正式名称的非常年性支流，流域面积达2.97 km²，流域内分布有落叶阔叶林，隶属于坎伯兰高原（Cumberland Plateau）地貌分区。 该流域临近阿拉巴马州的埃斯蒂尔福克（Estillfork），海拔范围介于211米至550米之间，作为田纳西河大流域体系内佩恩特罗克河的支流存在。 该区域属亚热带湿润气候，1月与7月的日均气温分别为4.4℃与25.4℃，年平均降水量达1390 mm/yr。 所有数据均提取自美国地质调查局（USGS）国家地图下载器v2.0（USGS National Map Downloader v2.0）提供的数字高程模型（Digital Elevation Model, DEM）栅格数据。此外，配套的watershed_PRF.zip与streamnetwork_PRF.zip压缩包分别包含流域边界矢量多边形与已勾绘河网矢量线的.shp格式文件。 本流域以出口点位（站点编号：PRM01）作为汇水边界，河网勾绘采用60000栅格单元的阈值，以最大程度匹配野外实地观测得到的地貌河网形态。
