Permafrost is a sub-ground phenomenon and therefore cannot be directly observed from
space. It is an Essential Climate Variable and associated with climate tipping points. Multi …

Arctic permafrost, the largest non-seasonal component of Earth's cryosphere, contains a
substantial climate-sensitive carbon pool. The existence of a global tipping point, a warming …

Due to the increasing air temperatures, retrogressive thaw slumps (RTSs) have become
more common on the Qinghai–Tibet Plateau (QTP), but their inventory, frequency, and …

In a warming Arctic, permafrost-related disturbances, such as retrogressive thaw slumps
(RTS), are becoming more abundant and dynamic, with serious implications for permafrost …

Understanding the wildfire extent and post-fire vegetation recovery is critical for fire and
forest management. Remote sensing imagery is widely used in wildfire detection because it …

Monitoring global lake/reservoir water level changes is needed to understand the global
water cycle and investigate its potential drivers. The existing global water level products only …

Thaw slumps are clear indicators of rapid permafrost degradation. They form preferentially in
near-surface ice-rich permafrost of northern high latitudes after initial thermal disturbance by …

Nitrogen regulates multiple aspects of the permafrost climate feedback, including plant
growth, organic matter decomposition, and the production of the potent greenhouse gas …

The northern permafrost region has been projected to shift from a net sink to a net source of
carbon under global warming. However, estimates of the contemporary net greenhouse gas …

Characteristics of active layer processes depend on the conditions of the ground surface,
coupled water-heat balance, soil hydrology, and soil properties under frozen and thawed …
