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,

Glacier‐Atmosphere Interactions and Feedbacks in High‐Mountain Regions ‐ A Review

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Mountain glaciers are among the natural systems most vulnerable to climate change. However, their interactions with the atmosphere are complex and not fully understood. These interactions can trigger rapid adjustments and climate feedbacks that either amplify or attenuate atmospheric signals, influencing both glacier response and large‐scale ...

Suivi des ressources en eau par télédétection multi-capteur: désagrégation de données spatiales et modélisation descendante des processus hydrologiques [PDF]

, 2016
Certaines variables extraites par télédétection sont potentiellement très utiles en hydrologie. C'est le cas de l'humidité du sol en surface qui contrôle la partition des précipitations en évaporation du sol, infiltration et ruissellement de surface.

Along the Silenced Footsteps of Latin American Pastoralists: From Mexico to Argentina, a Journey Through Pastoral Systems in Latin America

The Journal of Latin American and Caribbean Anthropology, Volume 31, Issue 1, March 2026.
ABSTRACT Pastoralism worldwide faces a complex landscape of increased pressures and exclusion. Beyond ecological and economic challenges, pastoralists suffer eroding cultural identity, limited generational renewal, and political marginalization. Yet pastoral livelihoods are increasingly recognized as stewards of sustainable futures and amongst the best

Projected Late 21st Century Warming Unprecedented in Northwest China in a Holocene Context

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Northwest China is facing socio‐environmental challenges linked to ongoing climatic warming. However, a scarcity of regional paleorecord syntheses limits our understanding of natural long‐term climate variability in the region and hinders the contextualization of contemporary warming.

Conception d'un filtre hyperfréquence analogique pour le traitement de données lidar modulé

, 2011
National audienceLa détection sous-marine par méthode optique LIDAR (LIght Detection And Ranging) fait actuellement l'objet de nombreuses recherches. L'inconvénient majeur de cette technique est le fait que la rétrodiffusion volumique de l'eau de mer ...

Pivotal Role of Cloud‐Planetary Boundary Layer Coupling to Explain Contrasting Aerosol‐Cloud Relationships

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract The radiative effect of aerosol on cloud albedo via altering cloud droplet effective radius (re) is a major uncertainty in the Earth's climate system. Remote sensing studies have reported either negative or positive relationships between re and aerosol number concentration (Na) or other aerosol proxies.

Diverging Spring Warming and Growing Season Shifts Across Eurasia and North America Under Future Climate

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Springtime warming over Northern Mid‐High‐latitude Land profoundly affects plant life cycles and water resources, yet large model uncertainty limits climate risk assessment. Here, we develop a novel emergent constraint that targets the key uncertainty source—model divergence in surface‐albedo feedback linked to historical snowmelt sensitivity.

Low Cloud Dispersion Effects by Anthropogenic Aerosols in Polluted Air

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Aerosol–cloud interactions (ACI) are a major source of uncertainty in anthropogenic climate forcing. Anthropogenic aerosols modulate the cloud albedo by impacting the relative dispersion (ε) of cloud droplet size distributions (CDSDs), known as the dispersion effect.
