Environmental parameter dataset of Chinese Lakes from 2014 to 2023

The dataset provides monthly data of eight key water quality parameters and surface water temperature for 82,759 lakes in China from 2014 to 2023. The water quality data were generated and published by Luan et al. (2025) in Scientific Data 12: 572, https://doi.org/10.1038/s41597-025-04915-y. Air temperature was used as a proxy for surface water temperature. It was provided by the National Centers for Environmental Information under the National Oceanic and Atmospheric Administration (https://www.ncei.noaa.gov/data/global-summary-of-the-day/archive/, accessed 8 January 2026). The environmental parameters included are: Dissolved oxygen (DO; mg/L) Total nitrogen (TN; mg/L) Chemical oxygen demand (CODMn; mg/L) Dissolved organic carbon (DOC; mg/L) pH Electrical conductivity (EC; S/m) Total phosphorus (TP; mg/L) Turbidity (Tur; JTU) Water temperature (Temp; °C) The data are stored in CSV format (provided as ZIP file) and include monthly values for each lake along with corresponding geographic coordinates (latitude and longitude).本数据集涵盖2014至2023年中国82759个湖泊的8项关键水质参数及地表水温度月度监测数据。该水质数据集由Luan等人（2025）生成并发表于学术期刊《科学数据》（Scientific Data）第12卷第572页，DOI链接为https://doi.org/10.1038/s41597-025-04915-y。 本研究以气温作为地表水温度的替代指标，气温数据由美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）下属的国家环境信息中心提供，数据归档地址为https://www.ncei.noaa.gov/data/global-summary-of-the-day/archive/，数据获取时间为2026年1月8日。 本次数据集包含的环境参数如下： 溶解氧（Dissolved Oxygen, DO；单位：mg/L） 总氮（Total Nitrogen, TN；单位：mg/L） 化学需氧量（Chemical Oxygen Demand, CODMn；单位：mg/L） 溶解有机碳（Dissolved Organic Carbon, DOC；单位：mg/L） pH值 电导率（Electrical Conductivity, EC；单位：S/m） 总磷（Total Phosphorus, TP；单位：mg/L） 浊度（Turbidity, Tur；单位：JTU） 水温（Water Temperature, Temp；单位：°C） 该数据集以CSV格式存储（以ZIP压缩包形式提供），包含各湖泊的月度参数值及其对应的地理坐标（纬度与经度）。
