With PNNL's climate model, Smith created more than 1,400 potential scenarios to reflect the many possibilities surrounding aerosols, tiny particles including soot that float in the atmosphere.

It then combines with pollutants from combustion — mainly nitrogen oxides and sulfates from vehicles, power plants and industrial processes — to create tiny solid particles, or aerosols, no more than 2.5 micrometers across, about 1/30 the width of a human hair.

The team started by looking at the formation of the very small particles — a process called aerosol nucleation — by mimicking atmospheric conditions inside an ultraclean steel «cloud chamber», which Kirkby says is the cleanest ever created.

A new simulation created by scientists at NASA's Goddard Space Flight Center in Greenbelt, Md., reveals just how far around the globe such aerosol particles can fly on the wind.

Aerosol chemist Markus Ammann of the Paul Scherrer Institute in Villigen, Switzerland, and his colleagues, suspected that soot particles — spewed when fossil fuels are burned — might have a hand in creating nitrous acid.

PUMPING aerosol particles into the atmosphere to create a sunshade could take a heavier toll on solar power generation than expected.

Secondary organic aerosols, or SOAs, are created when hydrocarbon gases, given off by everything from pine trees to snow blowers, undergo a series of chemical reactions in the atmosphere to produce particles.

Fast forward to 2006: Svensmark and colleagues» laboratory experiments show that highly ionizing radiation can create ultra-small aerosol particles.

Press release (emphases added):... scientists have succeeded for the first time in directly observing that the electrically charged particles coming from space and hitting the atmosphere at high speed contribute to creating the aerosols that are the prerequisites for cloud formation.

It then combines with pollutants from combustion — mainly nitrogen oxides and sulfates from vehicles, power plants and industrial processes — to create tiny solid particles, or aerosols, no more than 2.5 micrometers across, about 1/30 the width of a human hair.

Such clouds contain aerosols — tiny particles suspended in the air that are known to create a general cooling effect that could mitigate global warming.

Dirt particles in the atmosphere, especially sulphate aerosols, have created a certain cooling effect and has prevented a stronger temperature increase at the moment.

The cosmic ray particles work let's say like a «glue» that puts together all the already formed condensation nuclei in the atmospheric air, creating therefore bigger condensation nuclei and finally the clouds, or the cosmic particles act as aerosols on their own, on which the water vapour condenses?

It has been hypothesized that galactic cosmic rays (GCR) create atmospheric ions which facilitates aerosol nucleation and new particle formation with a further impact on the cloud formation (Kazil et al., 2012; Pierce and Adams, 2009).

In the United States, new research from the City College of New York on the effects of particle pollution on weather patterns around Manhattan has shown that aerosols can either increase or decrease local rainfall, sometimes creating situations where one area will be deluged while a neighboring town will remain dry.
