Volatile organic compounds (VOCs) are important precursors for secondary organic aerosol (SOA) formation. As a significant aromatic compound of VOC, 1,3,5-trimethylbenzene (1,3,5-TMB, C9H12) mainly comes from vehicle exhaust, ...
A new study finds that in the near future, the warming effect of anthropogenic aerosol reduction will superimpose on the cooling effect caused by the CO2 reduction, leading to greater surface temperature increase, delayed ...
Earth's atmosphere is full of various gasses. Besides nitrogen, oxygen, and carbon dioxide in the troposphere, it also contains other molecules or trace gasses that can be neutral, beneficial, or harmful to our health. Whence ...
Global lightning activity dropped almost 8% during the 2020 COVID-19Â lockdowns, according to new research being presented at the AGU Fall Meeting 2021 in New Orleans. The cause of the drop appears to be a connection between ...
When ocean waves break, microscopic particles break free into the air. For beachgoers, aerosolized sea salts contribute to the tousled "beach hair" look. But other compounds found in seawater, including perfluoroalkyl substances ...
Climate models are digital simulations of the Earth's climate system. These models calculate the interactions of various drivers of climate, such as land, sea, atmosphere, and humidity among others and forecast the future ...
Air pollution is responsible for 7 million premature deaths around the world every year, according to the World Health Organization. That's roughly the same number of people who die from smoking or malnutrition. The damaging ...
In May 2021, the Centers for Disease Control officially recognized that SARS-CoV-2—the virus that causes COVID-19—is airborne, meaning it is highly transmissible through the air.
Joining the global effort to curb air pollution, researchers at Texas A&M University have developed computational tools to accurately assess the footprint of certain organic atmospheric pollutants. Their simulation, described ...
More than half of the sun-like star systems surveyed in the Milky Way harbor a mysterious type of planet unlike any in our own solar system.
