GLOBal river SALiniTy and associated ions (GlobSalt)
收藏资源简介：
To assess how pervasive this issue is globally and identify salinization hotspots, we compiled global data on river salinity and associated ions. We retrieved information from 62 different datasets (including WQP, Waterbase), harmonized it and merged it with watersheds from HydroATLAS to summarize information at the sub-catchment scale. Our global data set (GlobSalt database) features 13 parameters: electrical conductivity (EC), pH, major ions (Na+, K+, Mg2+, Ca2+, Cl-, SO42-, SiO32-), total organic carbon, nitrate, ammonium, and phosphate. GlobSalt contains approximately fifteen million records on a monthly scale for two hundred seventy thousand river stations from 1980 to 2023 from all continents except Antarctica. The GlobSalt_data.CSV file contains processed observation data (*_GlobSalt.csv) along with corresponding metadata (observation site information, etc.) for 13 different water quality parameters
为评估该问题在全球范围内的普遍程度并识别盐碱化热点区域，我们整合了全球河流盐度及相关离子数据。我们从62个不同数据集（包括WQP、Waterbase）中获取信息，对其进行标准化整合，并与HydroATLAS的流域数据进行匹配，以子汇水区尺度汇总相关信息。本全球数据集（GlobSalt数据库）包含13项参数：电导率（electrical conductivity, EC）、pH值、主要离子（Na+、K+、Mg2+、Ca2+、Cl-、SO42-、SiO32-）、总有机碳、硝酸盐、铵盐以及磷酸盐。GlobSalt涵盖了1980年至2023年间，除南极洲外所有大洲的27万个河流监测站点的月度尺度数据，共计约1500万条记录。 GlobSalt_data.CSV文件包含处理后的观测数据（*_GlobSalt.csv）以及对应13项水质参数的元数据（监测站点信息等）
