This dataset contains various hydrometeorological elements including precipitation, discharge, water level, wind speed and direction, air temperature and humidity, etc. These elements are of great significance for studying the hydrological cycle, climate change and their impacts on water resources. Precipitation data helps understand precipitation patterns and trends; discharge and water level data can be used to analyze river flow characteristics and flood risks; wind speed and direction data contributes to studying the impacts of wind on water body evaporation and precipitation distribution; air temperature and humidity data can be used to evaluate evaporation and transpiration. Data sources: Six newly established glacial meltwater hydrological monitoring stations in the Qinghai-Tibet Plateau, namely the sources of the Yarlung Zangbo River, Lancang River, Heihe River, Niyang River, Tarim River and Kaidu River. Data were directly collected and exported on-site using hydrological survey instruments. Data processing methods include data cleaning, missing value imputation, outlier detection and data storage. First, raw data is cleaned to remove noise and invalid data, ensuring data accuracy and consistency. Second, interpolation or other statistical methods are used to fill missing values to ensure data integrity. Third, statistical analysis and algorithms are applied to detect and handle outliers in the data, avoiding their adverse impacts on analysis results. Finally, the processed data is stored in a database for subsequent query and analysis. In terms of data quality, the dataset covers the period from January 1, 2022 to December 31, 2024, with a minimum temporal resolution of daily. Some data are available at 5-minute, hourly, 3-hour intervals, meeting the requirements of different research needs. Data integrity is ensured through data cleaning and missing value imputation. Data accuracy and consistency are guaranteed through strict quality control and verification. The data comes from advanced hydrological survey instruments and has undergone scientific processing and storage, resulting in high reliability. This dataset has broad prospects in hydrological research and applications. Analysis of these data can improve the understanding of hydrological processes in river basins and support flood warning and disaster prevention and mitigation work. In addition, these data can also be used for water resources management, ecological environment protection and climate change research, providing scientific basis for relevant decision-making. In the future, with the continuous accumulation of data and the advancement of analysis methods, this dataset will provide more abundant and accurate information support for hydrological scientific research and engineering practice.
