Change in snow phenology and its potential feedback to temperature in the Northern Hemisphere over the last three decades

, 2013
Trends in the duration or extent of snow cover are expected to feedback to temperature trends. We analyzed trends in dates of onset and termination of snow cover in relation to temperature over the past 27 years (1980–2006) from over 636 meteorological ...

Reduced snow cover at the alpine treeline: resistance and recovery of saplings

New Phytologist, EarlyView.
Summary At high elevations, tree saplings and shrubs are usually protected by mid‐winter snow cover, although climate change is expected to extend the snow‐free (SF) period. Exposure to winter drought, freeze–thaw events and freezing temperatures will therefore increase, inducing damages to the hydraulic system and to living cells, resulting in reduced

Dual Polarimetric Radar Vegetation Index for monitoring forest moisture stress using time series of Sentinel‐1 SAR data

Plant Biology, EarlyView.
This study demonstrates the potential of the Sentinel‐1 Dual Polarimetric Radar Vegetation Index, combined with climate variables and the Standardized Precipitation–Evapotranspiration Index, to effectively detect and monitor drought‐induced stress in temperate broadleaf deciduous forests.

Near-surface remote sensing of spatial and temporal variation in canopy phenology [PDF]

, 2009
There is a need to document how plant phenology is responding to global change factors, particularly warming trends. “Near-surface” remote sensing, using radiometric instruments or imaging sensors, has great potential to improve phenological monitoring ...

Recurrent hot droughts cause persistent legacy effects in a temperate Scots Pine forest

Plant Biology, EarlyView.
A series of hot drought events caused persistent legacy effects in a Scots Pine forest, with severe negative impacts on ecosystem carbon fluxes. Abstract Recent hot‐dry events have caused significant impacts and legacy effects in temperate ecosystems. Here, we investigate legacy effects of the 2018 hot drought on a Pinus sylvestris L.

Phenology and carbon dioxide source/sink strength of a subalpine grassland in response to an exceptionally short snow season

Environmental Research Letters, 2013
Changes in snow cover depth and duration predicted by climate change scenarios are expected to strongly affect high-altitude ecosystem processes. This study investigates the effect of an exceptionally short snow season on the phenology and carbon dioxide

Frozen Soil Hydrological Processes and Their Effects: A Review and Synthesis

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Frozen soils, including seasonally frozen ground and permafrost, are rapidly changing under a warming climate, with cascading effects on water, energy, and carbon cycles. We synthesize recent advances in the physics, observation, and modeling of frozen‐soil hydrology, emphasizing freeze–thaw dynamics, infiltration regimes and preferential flow,

Fingerprint of rice paddies in spatial-temporal dynamics of atmospheric methane concentration in monsoon Asia. [PDF]

, 2020
Agriculture (e.g., rice paddies) has been considered one of the main emission sources responsible for the sudden rise of atmospheric methane concentration (XCH4) since 2007, but remains debated.

Systematic Benchmarking of Climate Models: Methodologies, Applications, and New Directions

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract As climate models become increasingly complex, there is a growing need to comprehensively and systematically assess model performance with respect to observations. Given the increasing number and diversity of climate model simulations in use, the community has moved beyond simple model intercomparison and toward developing methods capable of ...
