The data released this time is a 30 minute land surface process observation dataset for lakes at the source of the Yellow River, mainly from three observation points in the Eling Lake Basin. Eling Lake is the largest freshwater lake on the Qinghai Tibet Plateau, and together with the neighboring Zhaling Lake, it forms the "sister lake" at the source of the Yellow River. It has been included in the list of internationally important wetlands and is also the core area of Sanjiangyuan National Park. Since 2010, Ruoergai Station has established three observation points in the Erling Lake Basin: grassland, lake surface, and lakeside. It has carried out long-term positioning monitoring of turbulent flux, radiation flux, 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 for atmospheric interactions between plateau lakes. The data released this time covers the period from 2012 to 2019, with a time resolution of 30 minutes, aiming to provide a basis for the observation and analysis of lake land surface processes on the Qinghai Tibet Plateau, as well as the evaluation and development of numerical simulations.
