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

Modulation of Stratosphere‐to‐Troposphere Transport of Ozone by North Pacific Weather Patterns

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Stratosphere‐to‐troposphere transport (STT) of ozone is a major natural source of tropospheric ozone and is tightly linked to both stratospheric and tropospheric circulations. However, the complex interactions of drivers make it challenging to understand the subseasonal variability of STT.

Weak Tropical Tropospheric OH Response to Idealized ENSO

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The hydroxyl radical (OH) is a key oxidant for methane. Previous studies suggest that OH exhibits interannual variability linked to the El Nino–Southern Oscillation (ENSO), but the sign, magnitude, and underlying mechanisms of this response remain uncertain.

Lidar Ratios and Fluorescence Properties of Stratospheric Volcanic Sulfate

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract From January to June 2025, a stratospheric sulfate layer originating from the eruptions of the Ruang volcano in April 2024 could be observed with a multi‐wavelength Raman and fluorescence lidar over Leipzig, Germany. The aerosol‐optical depth of the stratospheric volcanic sulfate was <0.02 ${< } 0.02$, decreasing with time.

Intensification of the North Pacific Storm Track in the Mid‐1980s: Internal Variability Versus External Forcing

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The mid‐tropospheric winter North Pacific storm track (NPST) underwent an interdecadal transition from weak to strong in the mid‐1980s and exhibited a significant intensification trend. Using climate model outputs, this study investigates the contributions of external forcing and internal variability to the NPST intensification.
