Snow Cover Dynamics and Environmental Coupling Regulate Freezing Intensity Across China's Frozen Ground Regions

open access: yesEarth's Future, Volume 14, Issue 6, June 2026.
Abstract Climate warming and increasingly frequent hydroclimatic extremes are altering snowfall regimes and snow cover dynamics, with important implications for frozen‐ground stability. Yet the combined effects of snow cover and environmental controls on ground thermal conditions remain poorly constrained.

Physically Consistent Synthesis of Tropical Cyclone Microwave Brightness Temperatures From Geostationary Infrared Observations

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Analyzing the evolution of Tropical Cyclones (TCs) is critical for understanding their structure and intensity, but it has been limited by observational constraints. Spaceborne passive microwave (PMW) observations can penetrate both non‐precipitating and precipitating clouds and provide information on the vertical distribution of hydrometeors ...

Soft Tissue Sarcoma Burden and Research Productivity: Global Patterns and Disparities, 1990–2021

open access: yesHealth Science Reports, Volume 9, Issue 5, May 2026.
ABSTRACT Background Soft tissue sarcoma (STS) is a rare and diverse type of cancer, with a disproportionate incidence and limited global epidemiological studies. This study aims to analyze the long‐term trends and epidemiological features of the global burden of STS from 1990 to 2021 and to reveal the global research productivity on STS.

Roadmap for leveraging satellite data to advance soil moisture monitoring in Mainland Southeast Asia

open access: yesVadose Zone Journal, Volume 25, Issue 3, May/June 2026.
Abstract Soil moisture monitoring is vital for Mainland Southeast Asia (MSEA), a region that plays a pivotal role in global agricultural production. Strong reliance on rain‐fed agriculture, combined with frequent hydroclimatic extremes, makes MSEA one of the world's most climate‐sensitive regions.
