Influence of Variations in Gravity Wave Properties on Cirrus Ice Number Concentrations Produced by Homogeneous Freezing in the Tropical Tropopause Layer

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract In this study, we examine the impact of variations in gravity wave properties on the ice crystal number concentrations in the tropical tropopause layer (TTL). Analysis of quasi‐Lagrangian superpressure balloon measurements from the Stratéole‐2 campaign shows that high‐frequency waves dominate the occurrence of relatively large vertical wind ...

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 ...

An Evaluation of WRF‐Chem's Performance in Simulating PM2.5 in West African Cities

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract West Africa experiences some of the highest particulate pollution levels globally due to Saharan dust, biomass burning and urban emissions. Despite the severe health burden, air quality monitoring remains sparse. This study evaluates WRF‐Chem's performance in simulating PM2.5 levels across seven West African cities in 2021 using newly ...

Urban Land Surface Effects on Summertime Clouds and Moist Convection in Houston Under Different Synoptic Conditions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract Urban landscapes modify cloud formation and convection through complex thermodynamic and aerodynamic processes; however, their influence under different synoptic regimes remains poorly understood. This study investigates the impact of the Houston metropolitan area on summertime cloud cover and convective cell characteristics using a ...

Making a Dust Source Map: Can We Build, Implement, and Learn From a Reflectance Derived Sediment Supply Map in the Unified Forecast System (UFS)?

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract Mineral dust is an important part of the climate system we live in. Dust hotspots in deserts and arid regions emit tons of dust annually, influenced by local meteorology and soil characteristics. As one of the most abundant aerosols, it is important to characterize and define the climate and human impacts of dust.
