We present the first 90 m resolution dataset of active layer moisture covering the entire permafrost region of the Qinghai–Tibet Plateau. It was produced from 342 field observations (2009–2024) using four machine learning models combined through bias-aware fusion, and is accompanied by an area-of-applicability mask and per-pixel uncertainty estimates. The dataset is freely available at https://doi.org/10.12072/ncdc.permafrost.db7312.2026.

Snow on the Tibetan Plateau is often widespread in winter but usually shallow. We developed a benchmark that evaluates snow-covered area and snow depth together on each model’s native grid. Most CMIP6 models overestimate both variables in winter, especially over the western and high-elevation Plateau. The benchmark helps users choose snow products for cryospheric, hydrological and climate studies.

Since the early 1990s, the Siberian continuous permafrost has experienced markedly increased interannual variability in winter soil temperature. This heightened thermal instability is primarily driven by more variable winter snow depth, which insulates the soil. The influence extends meters deep, threatening permafrost stability and elevating risks of carbon release and ecosystem change under climate warming.

Climate change is caused by the accumulated heat in the Earth system, with the land storing the second largest amount of this extra heat. Here, new estimates of continental heat storage are obtained, including changes in inland-water heat storage and permafrost heat storage in addition to changes in ground heat storage. We also argue that heat gains in all three components should be monitored independently of their magnitude due to heat-dependent processes affecting society and ecosystems.

Short summary
Earth's climate is out of energy balance, and this study quantifies how much heat has consequently accumulated over the past decades (ocean: 89 %, land: 6 %, cryosphere: 4 %, atmosphere: 1 %). Since 1971, this accumulated heat reached record values at an increasing pace. The Earth heat inventory provides a comprehensive view on the status and expectation of global warming, and we call for an implementation of this global climate indicator into the Paris Agreement’s Global Stocktake.

Selin Co has exhibited the greatest increase in water storage among all the lakes on the Tibetan Plateau in the past decades. This study presents the first attempt to quantify the water contribution of ground ice melting to the expansion of Selin Co by evaluating the ground surface deformation since terrain surface settlement provides a
windowto detect the subsurface ground ice melting. Results reveal that ground ice meltwater contributed ~ 12 % of the lake volume increase during 2017–2020.

We characterized the multi-decadal geomorphic changes of a low-angle valley glacier in the East Kunlun Mountains and assessed the detachment hazard influence. The observations reveal a slow surge-like dynamic pattern of the glacier tongue. The maximum runout distances of two endmember avalanche scenarios were presented. This study provides a reference to evaluate the runout hazards of low-angle mountain glaciers prone to detachment.

Lack of a synthesis dataset of the permafrost state has greatly limited our understanding of permafrost-related research as well as the calibration and validation of RS retrievals and model simulation. We compiled this dataset, including ground temperature, active layer hydrothermal regimes, and meteorological indexes based on our observational network, and we summarized the basic changes in permafrost and its climatic conditions. It is the first comprehensive dataset on permafrost for the QXP.

This study reveals permafrost ground deformation from sub-daily to multi-year timescales at a central Tibetan Plateau supersite using satellite, contact, and non-contact field observations. A new automated system captured five-minute deformation changes, revealing distinct deformation processes during different freeze–thaw stages. The results evaluate different monitoring methods and provide a benchmark for understanding and interpreting permafrost change.

This study proposes a physically constrained joint electromagnetic inversion framework to quantify volumetric ground ice in alpine permafrost of the Yellow River source region. Integrating GPR full-waveform inversion with opposing coils TEM enables ice content estimation to 20 m depth.

Short summary
Water-soluble organic carbon (WSOC) is crucial in boreal forests, but its behavior across soil depths is poorly understood. Our study found that shallow soils contain complex WSOC molecules with high biodegradability, while deeper soils have simpler molecules that are also highly biodegradable. These results reveal the significant role of WSOC in carbon cycling across soil layers, improving our understanding of carbon dynamics in boreal ecosystems impacted by climate change.

We used the Moving-Grid Permafrost Model (MVPM) to simulate the permafrost thermal regime in West Kunlun (55,669 km², NW Qinghai–Tibet Plateau), driven by remote-sensing-based land surface temperature (LST; 1980–2022). The model showed high accuracy and stability. Despite ongoing warming (+0.40 °C per decade), permafrost extent remained stable, reflecting delayed deep responses. The permafrost thermal regime reveals altitude- and soil-dependent responses to climate change and offers valuable insights into thermal states in data-scarce regions.

This study provides baseline data of permafrost temperature at 15 m depth on the Qinghai–Tibetan Plateau (QTP) over the period 2010–2019 at a spatial resolution of nearly 1 km, using 231 borehole records and a machine learning method. The average MAGT15 m of the QTP permafrost was −1.85 °C, with 90 % of the values ranging from −5.1 to −0.1 °C and 51.2 % exceeding −1.5 °C. The data can serve as a crucial boundary condition for deeper permafrost assessments and a reference for model simulations.

Permafrost has been warming and thawing globally; this is especially true in boundary regions. We focus on the changes and variability in permafrost distribution and thermal dynamics in the northern limit of permafrost on the Qinghai–Tibet Plateau (QTP) by applying a new permafrost model. Unlike previous papers on this topic, our findings highlight a slow, decaying process in the response of permafrost in the QTP to a warming climate, especially regarding areal extent.

Short summary
We presented an 11-year time series of meteorological, active layer, and permafrost data at the Mahan Mountain relict permafrost site in northeastern Qinghai-Tibet Plateau. From 2010 to 2020, the increasing rate of active layer thickness was 1.8 cm-year and the permafrost temperature showed slight changes. The release of those data would be helpful to understand the impacts of climate change on permafrost in relict permafrost regions and to validate the permafrost models and land surface models.
We presented an 11-year time series of meteorological, active layer, and permafrost data at the...
