The data released this time is a 30-minute land surface process observation dataset of the source lake of the Yellow River, mainly from three observation points in the Ealing Lake basin. Ling Lake is the largest freshwater lake on the Qinghai-Tibet Plateau. Together with the neighboring Zhaling Lake, it forms a "sister lake" at the source of the Yellow River, and is listed on the list of internationally important wetlands. It is also the core area of Sanjiangyuan National Park. Since 2010, the Ruoergai Station has set up three observation points on grassland, lake surface and lakeside in the Ealing Lake basin, and carried out long-term positioning monitoring, including turbulence flux, radiation flux and conventional meteorological elements, soil water and heat, as well as irregular monitoring of atmospheric boundary layer and lake thermal processes, forming a relatively complete observation system of atmospheric interaction in plateau lakes. The data released this time range from 2012 to 2019, with a time resolution of 30 minutes, aims to provide a basis for the observation and analysis of lake land surface processes in the Qinghai-Tibet Plateau, and the evaluation and development of numerical simulation.
