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.

Indirect Impact of Atmospheric Aerosols in Idealized Simulations of Convective–Radiative Quasi Equilibrium. Part II: Double-Moment Microphysics
TL;DR: In this article, the authors extended the previous cloud-resolving modeling study concerning the impact of cloud microphysics on convective-radiative quasi equilibrium (CRQE) over a surface with fixed characteristics and prescribed solar input, both mimicking the mean conditions on earth.

Barry J. Huebert,Steve B. Howell,P. Laj,James E. Johnson,Timothy S. Bates,Patricia K. Quinn,Vladimir Yegorov,Antony D. Clarke,J. N. Porter +8 more
TL;DR: In this paper, the authors measured a wide variety of sulfur compounds simultaneously in the equatorial Pacific marine boundary layer, including dimethyl sulfide (DMS), sulfur dioxide (SO2), and size-resolved aerosol non-sea salt sulfate (NSS), and methane sulfonate (MSA).

Aerosol effect on droplet spectral dispersion in warm continental cumuli
Govindan Pandithurai,S. Dipu,Thara V. Prabha,R. S. Maheskumar,J. R. Kulkarni,Bhupendra Nath Goswami +5 more
TL;DR: In this paper, the authors investigated the dispersion effect and its implications for estimating aerosol indirect effects in continental cumuli and found that not only the cloud droplet number concentration but also the relative dispersion increases with the aerosol number concentration.

TL;DR: In this paper, the activation behavior of aerosol particles has been investigated during several Cloud and Aerosol Characterization Experiments conducted in winter and summer 2004 and winter 2005 at the high alpine research station Jungfraujoch ( 3580 m altitude, Switzerland).

TL;DR: In this article, the variation of aerosol indirect effects in climate models is investigated across different dynamical regimes, determined by monthly mean 500 hPa vertical pressure velocity (ω500), lower-tropospheric stability (LTS), and large-scale surface precipitation rate derived from several global climate models (GCMs), with a focus on liquid water path (LWP) response to cloud condensation nuclei (CCN) concentrations.

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.
