Abstract： The Himalayan region, represented by Mount Qomolangma, is not only a typical area where special atmospheric processes on the Tibetan Plateau (TP) are concentrated, but also an important research area for climate, ecology, and environmental changes. The Qomolangma Station for Atmospheric and Environmental Observation and Research, Chinese Academy of Sciences (abbreviated as QOMS) is located in the core area of Mount Qomolangma National Nature Reserve. It is dedicated to studying the complex terrain mountain atmospheric processes and environmental changes of the Third Pole of the Earth, focusing on the land-atmosphere interaction process on the TP under the background of climate change. Based on long-term positioning monitoring and field scientific observations of surface, atmosphere, environment, glaciers, ecology, and geophysical processes, a comprehensive land-atmosphere interaction observation system over the TP represented by QOMS has been developed and designed. Key parameters of surface features that influence the material and energy exchange between land and atmosphere in this region have been identified. The interaction processes between complex mountainous terrain of the plateau and the westerly large-scale atmospheric circulation and its impact on the development of the atmospheric boundary layer have been revealed. Remote sensing inversion algorithms and parameterization schemes for estimating surface energy fluxes in the region have been developed and verified, and a theory of pointface combination for satellite remote sensing inversion of complex land surface water and heat flux on the TP has been established. The establishment of the multi-time and space, multi-means, high-precision, and multi-element integrated observation platform has significantly improved the meteorological observation capabilities of the TP, especially in the Qomolangma region. It not only provides basic data for in-depth systematized research on the Earth system of the TP, but also makes up for long-term observation deficiencies on the plateau and has made QOMS an irreplaceable base for global Earth system science research in the Himalayan region, providing a support platform for understanding the role of the TP in global change and its response to global change.
