Sunlight has a major influence on chemical processes. Its high-energy UV radiation in particular is strongly absorbed by all materials and triggers photochemical reactions of the substances present in the air. A well-known ...
Sulfate-nitrate-ammonium (SNA) and other atmospheric aerosols play a significant role in influencing both atmospheric and environmental conditions. These aerosols impact climate directly through scattering and absorbing solar ...
School of Earth and Atmospheric Sciences researchers find dangerous sulfates are formed, and their particles get bigger, within the plumes of pollution belching from coal-fired power plants
Air pollution in China is generated from many sources and interacts chemically and physically within the atmosphere in ways that can be difficult to predict. The concept of the Air Pollution Complex was created to address ...
A research team led by Prof. Gao Xiaoming at the Anhui Institute of Optics and Fine Mechanics (AIOFM), Hefei Institutes of Physical Science (HFIPS) of Chinese Academy of Sciences (CAS) recently proposed a new dual-wavelength ...
Ammonia has been in the news because of its suitability as a hydrogen carrier and fuel, in addition to being a vital ingredient in fertiliser. Existing distribution networks and the ease of turning ammonia gas into a liquid ...
Ever since its launch in 1990, NASA's Hubble Space Telescope has been an interplanetary weather observer, keeping an eye on the largely gaseous outer planets and their ever-changing atmospheres. NASA spacecraft missions to ...
Researchers from the University of York have discovered why reducing particle pollution is actually increasing surface ozone pollution in some emerging economies, negatively impacting health, ecosystems and agriculture.
Aerosol products used in the home now emit more harmful volatile organic compound (VOC) air pollution than all the vehicles in the UK, new research shows.
Orbiting a red dwarf star 41 light-years away is an Earth-sized, rocky exoplanet called GJ 1132 b. In some ways, GJ 1132 b has intriguing parallels to Earth, but in other ways it is very different. One of the differences ...
