CLM - Streamflow unified NSW

## **Abstract** \n\nThe dataset was derived by the Bioregional Assessment Programme from the NSW streamflow dataset from NSW Office of Water. The source dataset is identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.\n\n\n\nA set of unified 6-category daily streamflow files for available stream gauging stations in the Tweed, Brunswick, Richmond and Clarence catchments, NSW.\n\n## **Purpose** \n\nTo determine the availability of good quality gauging data for each gauging station to meet AWRA calibration requirements\n\n## **Dataset History** \n\nThe New South Wales Office of Water (NOW) provides to the Bureau of Meteorology a copy of their hydstra surface water database. The last extract was received in July 2013. \n\nData was extracted from the Hydstra format to .csv files for surface water sites within the CLM sub-region as requested by the CLM project team. Quality codes have been included.\n\nWhere surface water quality data is available, this is included on a separate tab for each gauging station\n\n\n\nEach unified 6-category daily streamflow file was generated using the MATLAB script "Streamflow_QA_QC.m". The six categories are good, fair, poor, unverified, missing, and non-conformed.\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (2015) CLM - Streamflow unified NSW.

**摘要**
本数据集由生物区域评估计划（Bioregional Assessment Programme）基于新南威尔士州水务局（NSW Office of Water）的新南威尔士州径流数据集衍生而来。本数据集的源数据集与衍生制作流程分别可在本元数据声明的「谱系（Lineage）」字段与「历史（History）」字段中查询到。

本数据集包含新南威尔士州特威德（Tweed）、布伦瑞克（Brunswick）、里士满（Richmond）与克拉伦斯（Clarence）流域内现有水文测站的统一分类六类日径流文件。

**数据集用途**
本数据集用于评估各水文测站的高质量实测数据可获取性，以满足AWRA率定需求。

**数据集历史**
新南威尔士州水务局（NSW Office of Water，缩写NOW）曾向澳大利亚气象局提供其hydstra地表水数据库副本，最近一次数据提取包接收于2013年7月。
应CLM项目团队要求，研究人员将CLM子区域内的地表水监测点位数据从Hydstra格式导出为.csv格式文件，并附带质量编码。
若存在地表水水质数据，则将其以单独工作表的形式附于各水文测站的对应文件中。
所有统一分类的六类日径流文件均通过MATLAB脚本「Streamflow_QA_QC.m」生成，六类分别为优质（good）、合格（fair）、劣质（poor）、未验证（unverified）、缺失（missing）与不符合规范（non-conformed）。
