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.

Multisensor satellite observations of aerosol effects on warm clouds
TL;DR: In this article, a global multisensor satellite examination of aerosol indirect effects on warm oceanic clouds is presented, focusing on the water path response of cloud to aerosol burden, and a unique element of the study is a rigorous rain screening methodology that is utilized to separate the responses of nonraining and raining clouds.

J. C. Acosta Navarro,V. Varma,Ilona Riipinen,Øyvind Seland,Alf Kirkevåg,Hamish Struthers,Hamish Struthers,Trond Iversen,Hans-Christen Hansson,Annica M. L. Ekman +9 more
TL;DR: The Arctic region is warming considerably faster than the rest of the globe as discussed by the authors, with important consequences for the ecosystems and human exploration of the region, however, the reasons behind this phenomenon are unknown.

Yi Ming,Venkatachalam Ramaswamy +1 more
TL;DR: In this paper, a modified version of the Geophysical Fluid Dynamics Laboratory atmosphere general circulation model (AM2.1) coupled with a mixed layer ocean model is used to study the equilibrium temperature and hydrological responses to the total aerosol effects.

TL;DR: In this article, a comparative study of dust events on Earth and Mars was conducted to shed light on important physical processes of the weather and climate of both planets, and it was shown that terrestrial dust devils produce heat and dust fluxes two and five orders of magnitude larger than their background values.
Annual cycle of global distributions of aerosol optical depth from integration of MODIS retrievals and GOCART model simulations
Hongbin Yu,Robert E. Dickinson,Mian Chin,Mian Chin,Yoram J. Kaufman,Brent N. Holben,Igor V. Geogdzhayev,Michael I. Mishchenko +7 more
TL;DR: In this article, the authors provided a complete global coverage of an annual cycle of aerosol optical depth by combining the MODIS retrievals and Georgia Tech/Goddard Global Ozone Chemistry Aerosol Radiation and Transport (GOCART) simulations weighted with the uncertainties in each product.

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.
