Short summary
This study revealed the temporal variations of carbon fluxes, water flux, and water use efficiency (WUE) in alpine meadows across daily, monthly—seasonal, and inter-annual timescales. Confirmed that the driving factors of carbon-water coupling are different at different time scales. Quantified the alpine meadow as a multi-year carbon sink, providing a basis for predicting grassland ecosystem responses to future climate change on the Tibetan Plateau.

Short summary
Soil moisture and soil temperature (SMST) are important state variables for quantifying the heat–water exchange between land and atmosphere. Yet, long-term, regional-scale in situ SMST measurements at multiple depths are scarce on the Tibetan Plateau (TP). The presented dataset would be valuable for the evaluation and improvement of long-term satellite- and model-based SMST products on the TP, enhancing the understanding of TP hydrometeorological processes and their response to climate change.

Short summary
Wetland soils on the Qinghai–Tibetan Plateau contain layers that store and move water differently. Using soil measurements, evaporation experiments, and land surface simulations, we found that surface soils drained rapidly, while deeper soils released water more slowly and stored it longer. Representing these differences improved simulations of soil moisture and exchanges of water and heat with the atmosphere, helping land surface models better represent alpine wetlands.
