Geospatial Information, Metadata, and Maps for Global River Corridor Science Focus Area Sites (v3)

This dataset provides geospatial information, metadata, and maps for the Pacific Northwest National Laboratory (PNNL) River Corridor Science Focus Area (RC SFA; https://www.pnnl.gov/projects/river-corridor) sites. The RC SFA works to transform understanding of spatial and temporal dynamics in river corridor hydrobiogeochemical functions from molecular reaction to watershed and basin scales. The knowledge we gain is used to formulate and test hypotheses and to improve mechanistic representation of river corridor processes and their response to disturbances in multiscale models of integrated hydrobiogeochemical function. The data provided includes Site ID, latitude, longitude, stream name, and common ID (COMID) for sites used across the RC SFA. The COMID can be used to find and download data from NHDPlus (https://www.epa.gov/waterdata/nhdplus-national-hydrography-dataset-plus) and other platforms. The sites included are non-exhaustive. Sites (including past sites) will be added to this data package in the future. Data generated from the RC SFA can be accessed at https://data.ess-dive.lbl.gov/portals/PNNLRiverCorridorSFA. This dataset is comprised of one main data folder. The data folder consists of (1) file-level metadata; (2) data dictionary; (3) readme; (4) methods codes; (5) geospatial information for all RC SFA sites including International Generic Sample Number (IGSN); (6) maps of all sites and sites in Washington State, USA; and (7) a subfolder with the shapefile of all sites. All files are .csv, .pdf, .shp, .cpg, .dbf, .prj, .qmd, or .shx. This data package was originally published in April 2023. It was updated in June 2023 (v2; corrected and added/updated files) and again in December 2023 (corrected and added/updated files). See the change history section in the readme for more details.本数据集为美国太平洋西北国家实验室（Pacific Northwest National Laboratory，PNNL）河流廊道科学重点研究区（River Corridor Science Focus Area，RC SFA；网址：https://www.pnnl.gov/projects/river-corridor）的相关站点提供地理空间信息、元数据与地图文件。 RC SFA的核心研究目标是深化对河流廊道水文生物地球化学功能时空动态变化的认知，研究尺度涵盖从分子反应层级直至流域与盆地层级。本团队获取的相关认知与成果将用于构建与验证假说，并完善多尺度集成水文生物地球化学功能模型中河流廊道过程的机制表征及其对扰动的响应规律。 本数据集提供的字段涵盖RC SFA全域站点的站点编号、纬度、经度、溪流名称以及通用标识符（COMID）。其中COMID可用于从美国国家水文数据集增强版（NHDPlus，https://www.epa.gov/waterdata/nhdplus-national-hydrography-dataset-plus）及其他平台检索并下载对应数据。本数据集收录的站点并非全部，未来还将新增过往及新增站点至该数据包中。RC SFA产生的全部相关数据可通过https://data.ess-dive.lbl.gov/portals/PNNLRiverCorridorSFA获取。 本数据集由一个主数据文件夹构成，其内部包含：(1) 文件级元数据；(2) 数据字典；(3) 说明文档（readme）；(4) 方法代码；(5) 所有RC SFA站点的地理空间信息，包含国际通用样品编号（International Generic Sample Number，IGSN）；(6) 所有站点及美国华盛顿州境内站点的分布图；(7) 存储所有站点形状文件（shapefile）的子文件夹。所有文件格式包括.csv、.pdf、.shp、.cpg、.dbf、.prj、.qmd及.shx。 本数据包最初于2023年4月发布，分别于2023年6月（版本2，修正、新增并更新文件）及2023年12月（修正、新增并更新文件）完成两次更新。详细更新内容请参见说明文档中的变更历史章节。
