Aerosols, cloud microphysics, and fractional cloudiness.
TL;DR: Increases in aerosol concentrations over the oceans may increase the amount of low-level cloudiness through a reduction in drizzle—a process that regulates the liquid-water content and the energetics of shallow marine clouds—to contribute to a cooling of the earth's surface.

Abstract: Increases in aerosol concentrations over the oceans may increase the amount of low-level cloudiness through a reduction in drizzle—a process that regulates the liquid-water content and the energetics of shallow marine clouds. The resulting increase in the global albedo would be in addition to the increase due to enhancement in reflectivity associated with a decrease in droplet size and would contribute to a cooling of the earth9s surface.

TL;DR: In this paper, the authors evaluate the aerosol schemes as implemented in the physical and Earth system models, HadGEM3-GC3.1 and UKESM1, which are contributing to the 6th Coupled Model Intercomparison Project (CMIP6).

TL;DR: In this article, the authors used the MODIS satellite data and two global aerosol models to investigate the relationship be- tween aerosol optical depth (AOD) and cloud parameters that may be affected by the aerosol concentration.
Have Australian rainfall and cloudiness increased due to the remote effects of Asian anthropogenic aerosols
Leon D. Rotstayn,Wenju Cai,Martin Dix,Graham D. Farquhar,Yan Feng,Paul Ginoux,Michael Herzog,Akinori Ito,Joyce E. Penner,Michael L. Roderick,Minghuai Wang +10 more
TL;DR: The authors showed that anthropogenic aerosol changes in 20th century simulations of a global climate model gives increasing rainfall and cloudiness over Australia during 1951-1996, whereas omitting this forcing gives decreasing rainfall and cloudsiness.

The dependence of aerosol effects on clouds and precipitation on cloud-system organization, shear and stability
Seoung Soo Lee,Seoung Soo Lee,Leo J. Donner,Vaughan T. J. Phillips,Vaughan T. J. Phillips,Yi Ming +5 more
TL;DR: In this article, the authors investigated the effect of aerosol concentration on precipitation suppression in stratiform clouds and showed that increasing aerosol can either decrease or increase precipitation for an imposed large-scale environment supporting cloud development.

Aerosol indirect effect from turbulence-induced broadening of cloud-droplet size distributions
Kamal Kant Chandrakar,Will Cantrell,Kelken Chang,David Ciochetto,Dennis Niedermeier,Dennis Niedermeier,Mikhail Ovchinnikov,Raymond A. Shaw,Fan Yang +8 more
TL;DR: The result underscores the importance of droplet size dispersion for aerosol indirect effects: increasing aerosol concentration changes the albedo and suppresses precipitation formation not only through reduction of the mean droplet diameter but also by narrowing of the droplets size distribution due to reduced supersaturation fluctuations.

Oceanic phytoplankton, atmospheric sulphur, cloud albedo and climate
TL;DR: The major source of cloud-condensation nuclei (CCN) over the oceans appears to be dimethylsulphide, which is produced by planktonic algae in sea water and oxidizes in the atmosphere to form a sulphate aerosol as mentioned in this paper.

An assessment of the impact of pollution on global cloud albedo
TL;DR: In this paper, the authors studied the effect of pollution on global climate and found that the climate effect is comparable to that of increased carbon dioxide, and acts in the opposite direction, in that increasing absorption also attends increasing pollution.

The influence of entrainment on the evolution of cloud droplet spectra: I. A model of inhomogeneous mixing
TL;DR: In this article, the growth of condensate droplets rising above cloud base within small cumuli which are entraining undersaturated environmental air is investigated. But the authors assume that the mixing process is inhomogeneous.

Outlook for research on subtropical marine stratiform clouds
TL;DR: The first International Satellite Cloud Cover Project Regional Experiment (FIRE) as mentioned in this paper was proposed to develop physical models and parameterizations of fractional cloud cover over the Pacific Basin in order to determine fractional Cloud cover parameters, satellite observations by radar and lidar instruments combined with in situ measurements of the cloud-capped marine boundary layer.

Observations of marine stratocumulus clouds during FIRE
TL;DR: The first International Satellite Cloud Climatology Project Regional Experiment (FIRE) as discussed by the authors was used to study extensive fields of stratocumulus clouds off the coast of California, where measurements on the regional and detailed local scales were taken, allowing for a wide interpretation of the mean, turbulent, microphysical, radiative, and chemical characteristics of stratocalumulus.
