Observational Evidence for Relative Humidity Driving Black Carbon Mixing State and Absorption Enhancement in Urban Outflows

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Black carbon (BC)‐containing particles are the most strongly absorbing component of atmospheric aerosol, contributing to global warming. Quantifying their radiative effects remains challenging because BC absorption depends on their mixing state which can evolve through atmospheric aging.

Upper-atmosphere Aerosols: Properties and Natural Cycles [PDF]

, 1992
The middle atmosphere is rich in its variety of particulate matter, which ranges from meteorite debris, to sulfate aerosols, to polar stratospheric ice clouds. Volcanic eruptions strongly perturb the stratospheric sulfate (Junge) layer.

Contrail Formation Within Cirrus: Contrail Induced Perturbations and Cirrus Adjustments

Journal 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 ...

Laboratory Experiments on Savannah and European Boreal Forest Fire Emissions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract Landscape fire is among the largest sources of aerosols and trace gases globally. However, the emissions are highly variable and strongly affected by the type of biomass and combustion characteristics. We investigated the effect of combustion characteristics on the burning emissions from three biomass types: woody plants and grasses from ...

Dissolved Black Carbon in North Cascades Snow, Meltwater and a Downstream River

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract Quantification of black carbon on snow in the Cascade Range is needed due to increasing wildfire intensity and frequency. Here, the benzenepolycarboxylic acid (BPCA) molecular method was used to measure dissolved black carbon (DBC) in snow, nearby rivers, streams, and supraglacial melt collected in 2022 and 2023 from Mount Baker and Mount ...

Understanding Aitken Mode Aerosol Variability Over the Southern Ocean and Antarctica: Insights From Cloud Condensation Nuclei Data

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract Aitken mode aerosol particles can influence cloud properties and lifetime by acting as a reservoir of potential cloud condensation nuclei (CCN) that can replenish the CCN population against precipitation scavenging. However, data on Aitken‐mode aerosols in remote regions are limited. In this study, we developed a method to estimate Aitken mode
