An atmospheric scientist at The University of Alabama in Huntsville (UAH), a part of The University of Alabama System, has ...

Aerosol particles play a key role in cooling the planet. They can either directly affect how much sunlight ends up on the surface of the Earth or indirectly through cloud formation, to which they ...

Air quality and aerosol research is a multidisciplinary field that investigates the sources, composition, transformation, and impacts of tiny particulate and gaseous components in the atmosphere.

Oxidized organic molecules originating from the Amazon rainforest are crucial components contributing to the formation of aerosol particles in the tropical free troposphere, according to a new study ...

Secondary organic aerosol (SOA) represents a major constituent of tropospheric fine particulate matter, with profound implications for human health and climate. However, the chemical mechanisms ...

Nga Lee “Sally” Ng leads a new study investigating the formation and properties of secondary organic aerosol from the nitrate radical oxidation of two common monoterpenes, compounds found in many ...

Atmospheric aerosol particles exert a strong net cooling effect on the climate by making clouds brighter and more extensive, reflecting more sunlight back out to space. However, how aerosol particles ...

Researchers discovered that sulfur trioxide can form products other than sulfuric acid in the atmosphere by interacting with organic and inorganic acids. These previously uncharacterized acid sulfuric ...

Organic matter carried in rivers to the Russian part of the Arctic Ocean may be creating more clouds and keeping the region ...

A new study finds that, contrary to previous beliefs, large amounts of aerosol particles can form over vast areas of the West Siberian taiga in the spring. When temperatures rise, this can have a ...
