Significance of Size‐Dependent Hygroscopicity Parameterization for Aerosol‐Cloud Interactions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Aerosol‐cloud interactions (aerosol indirect effects) are the most significant source of uncertainties in the effective radiative forcing (ERF) due to aerosols which can act as cloud condensation nuclei (CCN). Uncertainties in the indirect effect can result from systematic uncertainties in aerosol water uptake (hygroscopicity).

Probability updating-based adaptive hybrid coding

Tongxin xuebao, 2008
A probability updating mechanism was proposed for entropy coding. To achieve the best coding efficiency,probability updating based huffman code and structured code were jointly used,and the best context model was selected according as the correlation of ...

Unveiling the Shortwave Absorption Spectra of Alumina Aerosols: Radiative Implications for Solar Radiation Modification

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Alumina is proposed for Stratospheric Aerosol Injection (SAI)‐based solar radiation modification due to its presumed ability to scatter sunlight strongly while absorbing weakly. Alumina is assigned negligible solar shortwave absorption in climate models; this assumption is not validated owing to technological challenges in quantifying its weak

Pragmatic Two‐Stage Design for Clinical Trials With Treatment Selection

Statistics in Medicine, Volume 45, Issue 18-19, August 2026.
ABSTRACT Clinical trials are inherently complex and become more challenging when selecting one treatment from many while also evaluating the efficacy. In this paper, we develop a pragmatic design that balances sample efficiency and practicality through a two‐stage sequential approach.

Features in the Visible Spectra of the Enceladus Particle Plume and E Ring: Potential Evidence of Organic Materials and/or Missing Sub‐Micron Particles

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Visible spectra of the Enceladus particle plume and E ring contain evidence for a change in spectral slope around 0.5 μm. This feature can be seen in data obtained by both the Visual and Infrared Mapping Spectrometer and Imaging Science Subsystem onboard the Cassini Spacecraft, and is consistent with the slope change seen in the surface ...

MAUSAM: An Observations‐Focused Assessment of Global AI Weather Prediction Models During the South Asian Monsoon

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract Past evaluation of artificial intelligence (AI) weather prediction has primarily relied on reanalyses, which can obscure important deficiencies due to prevailing biases in reanalyses themselves. Here, we present MAUSAM (Measuring AI Uncertainty during South Asian Monsoon), an evaluation of seven leading AI‐based prediction systems—FourCastNet,

Terrestrial Poor Ecohealth Areas Continue to Expand Across Asian Drylands

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract The 7th Rio declaration principle emphasizes global collaboration to protect and restore ecosystem health. While dryland ecosystem health (EH) remains critical to global sustainability agendas, its long‐term regional dynamics remain poorly constrained across the Asian drylands (AD), where land management decisions increasingly shape ecological
