Overwinter Warming Effects of Shrub Expansion in Arctic Permafrost Region

open access: yesEarth's Future, Volume 14, Issue 5, May 2026.
Abstract Numerous studies have shown that shrub cover in high‐latitude permafrost regions is increasing and the expansion is likely to continue in response to sustained temperature rise. However, knowledge gaps remain in how does the shrub expansion modulate the regional climate through large‐scale land‐atmosphere interactions.

Internal physiological drivers of leaf development in trees: Understanding the relationship between non‐structural carbohydrates and leaf phenology

open access: yesFunctional Ecology, Volume 40, Issue 5, Page 1151-1164, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant phenology is crucial for understanding plant growth and climate feedback. It affects canopy structure, surface albedo, and carbon and water fluxes. While the influence of environmental factors on phenology is well‐documented, the role of plant intrinsic factors ...

Multi‐Decadal Dynamics of Wetland Methane Emissions Revealed by Knowledge‐Guided Machine Learning

open access: yesGlobal Change Biology, Volume 32, Issue 5, May 2026.
Eddy covariance data for wetland CH4 emissions are fragmented, restricting the assessment of their long‐term dynamics. This study developed a knowledge‐guided machine‐learning framework that integrates field observations with biogeochemical principles to reliably reconstruct historical methane fluxes.

Global Diurnal Variation Characteristics of Aerosol Optical Depth From 32 Years of AERONET Observations

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Aerosols are ubiquitous microscopic particles in the atmosphere, and their diurnal variation characteristics reflect short‐term atmospheric changes that are crucial for climate monitoring and prediction. However, satellite, ground‐based, and reanalysis systems cannot simultaneously provide observational authenticity together with full temporal–

Contrail Formation Within Cirrus: Contrail Induced Perturbations and Cirrus Adjustments

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract Contrail formation constitutes a large fraction of the aviation climate impact. But only part of the effect has been studied in detail, as research focused on contrail formation in cloud‐free air. Even though it is known that the impact of contrail formation within cirrus can be detected in space‐born remote sensing data, little research has ...

The Various Influences due to Aerosol Depositions [PDF]

open access: yes, 2011
Recently the issue on glacier retreats comes up and many factors should be relevant to the issue. The absorbing aerosols such as dust and black carbon (BC) are considered to be one of the factors.

Spatiotemporal Variability of Seasonal Snow Cover over 25 Years in the Romanian Carpathians: Insights from a MODIS CGF-Based Approach

open access: yesRemote Sensing
Understanding long-term snow cover dynamics is essential in mountain regions with limited meteorological or in situ observations. This study examines seasonal snow cover evolution across the Romanian Carpathians (2000–2025) using daily MODIS/Terra ...
