Talladega Environmental Data (AIMS_SE_TAL_ENVI)

This resource includes static environmental data collected for the sensor and sampling locations in the Talladega research watershed (outlet location: 33.76219799, -85.59550775) in the Talladega National Forest (Cleburne 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 of Pendergrass Creek, and contains 0.92 km^2 of mixed coniferous and deciduous forest in the Piedmont Upland physiographic province. Located near Anniston, AL, the watershed spans an elevation range from 345 to 456 m above sea level and is a tributary to the Coosa River (within the larger Mobile-Tombigbee basin). The region has a humid subtropical climate, with mean daily January and July air temperatures of 5.3°C and 25.3°C respectively, and mean annual precipitation of 1400 mm/yr.

All data was extracted from Digital Elevation Model (DEM) rasters provided by the USGS National Map Downloader v2.0. Additionally, accompanying watershed_TAL.zip and streamnetwork_TAL.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: TLM01), and the stream network was delineated using a threshold of 10,000 cells to most closely match the field-observed geomorphic stream network.

本数据集涵盖为美国阿拉巴马州克莱本县塔拉德加国家森林内塔拉德加研究流域（出口点位：33.76219799, -85.59550775）的传感器与采样点位采集的静态环境数据，该数据集为“溪流干旱对微生物组的水生间歇性影响（Aquatic Intermittency effects on Microbiomes in Streams, 缩写AIMS）”项目的一部分，此项目由美国国家科学基金会（National Science Foundation, NSF）EPSCoR资助（项目编号：OIA 2019603）。
本项目旨在探究溪流干涸对堪萨斯州、俄克拉荷马州、阿拉巴马州及爱达荷州境内下游水质的影响，整合了水文、微生物组、大型无脊椎动物与生物地球化学相关数据集。该流域为彭德格拉斯溪的非常年性无名支流，流域面积0.92平方千米，地处皮德蒙特高地地貌区（Piedmont Upland physiographic province），覆盖针阔混交林。
该流域位于阿拉巴马州安尼斯顿附近，海拔范围为345至456米，是库萨河的支流（隶属于更大的莫比尔-通比格比流域（Mobile-Tombigbee basin））。本区域属亚热带湿润气候，1月与7月的日均气温分别为5.3℃与25.3℃，年平均降水量为1400毫米/年。
所有数据均源自美国地质调查局（United States Geological Survey, USGS）国家地图下载器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_TAL.zip与streamnetwork_TAL.zip压缩包分别包含流域边界多边形与划定河网矢量线的.shp格式文件。
本流域已被划定至出口点位（站点编号：TLM01），河网划定采用10000个栅格单元作为阈值，以最大程度匹配野外观测得到的地貌河网。
