Coarse-mode sea spray aerosols enhance warm rain formation in marine low clouds

Abstract. Precipitation in low clouds affects cloud responses to aerosol perturbations, thereby impacting aerosol radiative forcing of climate, a significant but indeterminate contribution to uncertainty in future warming. The onset of drizzle formation in marine low clouds may b...

Mitigating aviation’s environmental impact through alternative fuels and cleaner engines

Lean-burn engines are designed to reduce emissions, and sustainable alternative fuels provide additional potential for lowering particle emissions. However, the magnitude of the benefits from these mitigation levers remains poorly constrained, limiting robust predictions of aviat...

Upward transport and segregation of ice-nucleating particles in deep convective clouds

Abstract. Ice-nucleating particles (INPs) play a crucial role in Earth’s weather and climate by influencing cloud properties and precipitation. However, their abundance in the free troposphere, vertical distribution, and transport mechanisms are not well-characterized. This study...
