The alpine region is important in riverine and watershed ecosystems as a contributor of
freshwater, providing and stimulating specific habitats for biodiversity. In parallel, recent …

Variability of active layer thickness (ALT) in permafrost regions is critical for assessments of
climate change, water resources, and engineering applications. Detailed knowledge of ALT …

The response of seasonal soil freeze depth to climate change has repercussions for the
surface energy and water balance, ecosystems, the carbon cycle, and soil nutrient …

To investigate the thermal characteristics and dynamics of permafrost as well as seasonally
frozen ground over the upper reaches of the Heihe River Basin (URHR), an observation …

Vegetation is closely tied to climate change, hydrological processes, the carbon cycle, and
the energy balance. However, in cold regions, both climate and vegetation changes are also …

Active layer dynamics are basic information for understanding permafrost degradation, but
there are gaps in our knowledge of the active layer thickness (ALT) variations during the …

The active layer plays a key role in geomorphic, hydrologic, and biogeochemical processes
in permafrost regions. We conducted a systematic investigation of active layer thickness …

Warming and resulting degradation of near-surface permafrost in cold regions across the
globe has and will continue to lead to a series of hazards. These include land subsidence …

Due to sparse data and discontinuous time observations in the circum-Arctic region, freezing
index and thawing index, as useful indicators, are widely used in permafrost distribution …

There is an urgent need to evaluate the accuracy of reanalysis datasets to improve the
reliability of climate research, hydrology, ecology, engineering work, and so on. The ground …
