Streamflow measurements from four sites on the Tuolumne River in Yosemite National Park from Water Years 2002 to 2021

Regions with remote and complex terrain experience spatially varying streamflow patterns, but are often poorly sampled due to difficult access. This data package includes streamflow measurements collected using low-visibility and low-impact installations at four sites on the Tuolumne River in Yosemite National Park, for water years 2002 to 2021. The resulting data set offers a unique opportunity to explore hydrologic processes in complex terrain.This data package contains half-hourly recordings of unvented pressure, vented pressure, and water temperature are measured and used to estimate discharge and stage height. Discharge flags provide insight into data anomalies. This dataset is formatted in accordance with ESS-Dive's Hydrologic Monitoring and File Level Metadata Formats. It contains the following files:1) Folder containing four csv files of time series streamflow measurements (unvented pressure, vented pressure, estimated discharge, water temperature, stage height, and discharge flag) from four locations on the Tuolumne River2) Data dictionary (dd.csv) containing units, definitions, human readable column names, and data type for all column headers throughout the dataset3) File-level metadata (FLMD.csv) containing metadata for files contained in the dataset4) Installation methods (InstallationMethods.csv) containing metadata on sensor installation

地形偏远且地貌复杂的区域，径流格局存在空间异质性，但因通行条件受限往往采样不足。本数据包收录了2002至2021水文年期间，在约塞米蒂国家公园图奥勒姆河四个站点采用低可见度、低干扰安装方式采集的径流观测数据。本数据集为探究复杂地形下的水文过程提供了独特研究契机。
本数据包包含经实测得到的半小时级非通气压力、通气压力与水温记录，并以此估算流量与水位。流量标记可用于解析数据异常情况。本数据集严格遵循ESS-Dive的水文监测与文件级元数据格式规范进行组织。
其包含以下文件：
1) 包含四个CSV文件的文件夹，内含图奥勒姆河四个点位的时间序列径流观测数据，涵盖非通气压力、通气压力、估算流量、水温、水位及流量标记等字段
2) 数据字典（"dd.csv"），列明数据集所有列标题的单位、定义、易读列名与数据类型
3) 文件级元数据文件（"FLMD.csv"），收录数据集内各文件的元数据信息
4) 安装方法文件（"InstallationMethods.csv"），包含传感器安装相关的元数据信息
