Murray-Darling Basin stream gauge daily data from 1990 to 2011, NetCDF format

These four NetCDF databases constitute the bulk of the spatial and spatiotemporal environmental covariates used in a latent health factor index (LHFI) model for assessment and prediction of ecosystem health across the MDB. The data formatting and hierarchical statistical modelling were conducted under a CSIRO appropriation project funded by the Water for a Healthy Country Flagship from July 2012 to June 2014. Each database was created by collating and aligning raw data downloaded from the respective state government websites (QLD, NSW, VIC, and SA). (ACT data were unavailable.) There are two primary components in each state-specific database: (1) a temporally static data matrix with axes "Site ID" and "Variable," and (2) a 3D data cube with axes "Site ID", "Variable," and "Date." Temporally static variables in (1) include geospatial metadata (all states), drainage area (VIC and SA only), and stream distance (SA only). Temporal variables in (2) include discharge, water temperature, etc. Missing data (empty cells) are highly abundant in the data cubes. The attached state-specific README.pdf files contain additional details on the contents of these databases, and any computer code that was used for semi-automation of raw data downloads.

这四个NetCDF（网络通用数据格式）数据集构成了潜在健康因子指数（LHFI）模型所使用的绝大多数空间及时空环境协变量，该模型用于评估并预测MDB全域的生态系统健康状况。数据整理与分层统计建模工作依托澳大利亚联邦科学与工业研究组织（CSIRO）的拨款项目开展，该项目由“健康国家旗舰”水资源计划资助，实施周期为2012年7月至2014年6月。每份数据集均通过整合并对齐从对应州政府网站下载的原始数据构建而成，涉及的州包括昆士兰州（QLD）、新南威尔士州（NSW）、维多利亚州（VIC）与南澳大利亚州（SA）。（澳大利亚首都领地（ACT）数据无法获取。）每个州专属数据集均包含两大核心组成部分：(1) 以"站点ID（Site ID）"和"变量（Variable）"为轴的时空静态数据矩阵；(2) 以"站点ID（Site ID）"、"变量（Variable）"和"日期（Date）"为轴的三维数据立方体。(1) 中的时空静态变量涵盖地理空间元数据（所有州均包含）、流域面积（仅维多利亚州（VIC）与南澳大利亚州（SA）包含）以及河道距离（仅南澳大利亚州（SA）包含）。(2) 中的时空动态变量包含径流量、水温等观测指标。三维数据立方体中存在大量缺失数据（空单元格）。随附的各州专属README.pdf文件包含了本数据集的更多细节信息，以及用于原始数据半自动下载的相关计算机代码。
