Dataset of comparative observations for land surface processes over the semi-arid alpine grassland against alpine lake in the source region of the Yellow River

The source region of the Yellow River (SRYR) is located in the east of the Tibetan Plateau, accounting for 16.4% of the basin area and 38% of the runoff of the Yellow River basin, is the most important water conservation region of the Yellow River basin. Ngoring Lake is the largest freshwater lake on the SRYR. Since 2010, the Zoige Plateau Wetland Ecosystem Research Station of the Chinese Academy of Sciences has set up three observation sites in the grassland, lake surface and lakeside area of the Ngoring Lake basin, and carried out long-term monitoring of turbulence flux, radiation flux, conventional meteorological elements, soil water and heat, as well as irregular monitoring of atmospheric boundary layer and lake thermal processes. The data released this time were collected from three observation sites from 2012 to 2019, with a time resolution of 30 minutes. The data are composed of wind speed and direction, temperature, humidity, air pressure and precipitation data, four-component radiation data, multi-layer soil temperature and humidity and soil heat flux data, and turbulence data composed of sensible heat flux, and latent heat flux. This dataset includes the conventional meteorological data (Meteorology), soil data (SOIL) and turbulence data (Flux). The naming rule of the data in zip file is: (station name)-(data type)-(year).xlsx. These data can be widely used in the analysis of the characteristics of lake-atmosphere interaction on the Tibetan Plateau, evaluation and development of numerical simulation of lake and land surface processes in the Tibetan Plateau.

黄河源区（Source Region of the Yellow River, SRYR）地处青藏高原东部，占黄河流域总面积的16.4%、径流量的38%，是黄河流域最为重要的水源涵养区。鄂陵湖是该区域最大的淡水湖。自2010年起，中国科学院若尔盖高原湿地生态系统研究站在鄂陵湖流域的草原、湖面及湖滨区域布设3个观测站点，长期开展湍流通量（turbulence flux）、辐射通量（radiation flux）、常规气象要素、土壤水热状况监测，并对大气边界层（atmospheric boundary layer）与湖泊热过程进行不定期监测。本次发布的数据采集自2012至2019年三个观测站点的观测数据，时间分辨率为30分钟。该数据集包含风速风向、气温、湿度、气压与降水数据，四分量辐射数据，多层土壤温湿度及土壤热通量数据，以及由感热通量、潜热通量构成的湍流数据。本数据集涵盖常规气象数据（Meteorology）、土壤数据（SOIL）与湍流数据（Flux）。压缩包内数据的命名规则为：(station name)-(data type)-(year).xlsx。此类数据可广泛应用于青藏高原湖-气相互作用（lake-atmosphere interaction）特征分析、青藏高原湖泊与陆面过程（land surface process）数值模拟的评估与研发工作。
