Short summary
Current models and satellites struggle to accurately represent the land–atmosphere (L–A) interactions over the Tibetan Plateau. We present the most extensive compilation of in situ observations to date, comprising 17 years of data on L–A interactions across 12 sites. This quality-assured benchmark dataset provides independent validation to improve models and remote sensing for the region, and it enables new investigations of fine-scale L–A processes and their mechanistic drivers.

We developed a new model to better understand how water moves in a lake basin. Our model improves upon previous methods by accurately capturing the complexity of water movement, both on the surface and subsurface. Our model, tested using data from China's Qinghai Lake, accurately replicates complex water movements and identifies contributing factors of the lake's water balance. The findings provide a robust tool for predicting hydrological processes, aiding water resource planning.

Our team developed rSHUD v2.0, a toolkit that simplifies the use of the SHUD, a model simulating water movement in the environment. We demonstrated its effectiveness in two watersheds, one in the USA and one in China. The toolkit also facilitated the creation of the Global Hydrological Data Cloud, a platform for automatic data processing and model deployment, marking a significant advancement in hydrological research.

In this research, the effects of climate change on land surface and water cycle processes and the feedback of land-hydrological process to precipitation over the Source Region of the Yellow River. We find that the coupled process improves the simulation results for temperature, radiation, water-heat exchange fluxes, and soil temperature and moisture, but slightly increases the wet bias of the precipitation and evapotranspiration due to the consideration of lateral flow.

Short summary
As solar energy expands, its effects on ecosystems remain unclear, especially in fragile alpine regions like the Tibetan Plateau. We studied a photovoltaic power plant's impact on climate and soil. The panels increased radiation, reduced wind, and caused daytime warming but nighttime cooling. Soil stayed colder and wetter, extending the frozen period by 50 days. These changes may help stabilize permafrost but could also affect biodiversity and water cycles.
