Efficiency of organic aerosols as cloud condensation nuclei [PDF]

Eos, Transactions American Geophysical Union, 2012
Secondary organic aerosols—aerosols produced through chemical reactions in the atmosphere from volatile compounds—affect climate directly by reflecting sunlight and by acting as cloud condensation nuclei, promoting cloud formation. The efficiency with which different types of secondary organic aerosols act as cloud condensation nuclei is important to ...

Predominance of Externally Mixed Black Carbon Over the Tibetan Plateau During the Asian Summer Monsoon

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The mixing state of black carbon (BC) strongly influences its lifetime and radiative forcing over the Tibetan Plateau (TP). Previous observations, mostly conducted during the non‐monsoon season, suggested that thickly coated BC dominates due to long‐range transport from South Asia.

Coherent Turbulence Signatures Preceding Warm Rain Events From Collocated Cloud Radar and Wind Profiler Observations Across China

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Warm rain is plagued by a longstanding droplet growth bottleneck, one that turbulence may alleviate by enhancing droplet coalescence in the late condensation phase. Nevertheless, empirical observational support from multiple sites remains scarce. Here, we combine collocated nationwide millimeter cloud radars, radar wind profilers, Himawari‐8/9

A Hybrid Superdroplet–Bin Microphysics Approach Reveals How Large Salt Particles Trigger Rain in Non‐Precipitating Warm Convective Clouds

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract This study develops a Superdroplet‐Bin hybrid microphysics scheme within the Weather Research and Forecasting (WRF) model to investigate hygroscopic seeding of warm convective clouds. The Super‐droplet method describes 3D transport, deliquescence, condensation, and collision‐coalescence growth of seeding agents or solution droplets, while the ...

Supersaturation and Critical Size of Cloud Condensation Nuclei in Marine Stratus Clouds

Geophysical Research Letters
AbstractObservations of marine stratus clouds in clean air off the Californian coast reveal a functional relationship between the number of cloud condensation nuclei (CCN) and supersaturation. Satellite‐derived liquid droplet density estimates the number density of CCN.

Shipborne Measurements of Mineral Dust and Black Carbon Aerosols Over the Southern Ocean in the Austral Summer

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Atmospheric mineral dust and black carbon (BC) aerosols play important roles in the Earth's climate system, yet direct observations over the Southern Ocean (SO) are scarce. In this study, we present the characteristics of airborne water‐insoluble particles (WIPs) collected during a cruise of the R/V Shirase in the Australian and Indian sectors

Impact of Aerosols on Cloud Microphysical Processes: A Theoretical Review

Geosciences
The direct relationship between aerosols and clouds strongly influences the effects of clouds on the global climate. Aerosol particles act as cloud condensation nuclei (CCN) and ice nuclei (IN), affecting cloud formation, microphysics, and precipitation,

Cloud condensation nuclei activity at Jeju Island, Korea in spring 2005 [PDF]

Atmospheric Chemistry and Physics, 2008
We measured the number concentrations of cloud condensation nuclei (CCN) and the size distributions of CCN/CN (CN: condensation nuclei) ratios at supersaturations (<i>SS</i>s) of 0.097, 0.27, 0.58, and 0.97% at Jeju Island, Korea during March-

Extreme Atmospheric Moistening and Drying Events at Ny‐Ålesund and Their Relation to Weather Systems

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Understanding the role of water vapor in Arctic amplification requires a detailed evaluation of its spatio‐temporal variability. In this work, we use an integrated water vapor (IWV) data set from a ground‐based microwave radiometer at Ny‐Ålesund, Svalbard, covering 2012–2024, to characterize temporal IWV variability.
