The quest to identify a new way to potentially counter one of the world's most widely discussed solar geoengineering proposals has taken a new, exciting turn—raising questions about how future climate ...
Billions upon billions of soot particles enter Earth's atmosphere each second, totaling about 5.8 million metric tons a year—posing a climate-warming impact previously estimated at almost one-third ...
Atmospheric deposition plays an important role in the global distribution and long-range transport potential of micro- and nanoplastic particles. However, our mechanistic understanding of contributing ...
A high-altitude silver-colored aircraft takes off from a runway surrounded in snow. Trees and mountains. In 2023, researchers equipped NASA’s WB-57 high-altitude aircraft with a suite of instruments ...
The hygroscopic properties of atmospheric aerosols govern their ability to take up and release water vapour, with profound implications for air quality, human health and climate processes. Water ...
New high-altitude measurements have revealed a hidden population of extremely small, organic-rich aerosol particles in the lower stratosphere. The findings suggest that these ultrafine aerosols, ...
