The May 18, 1980, eruption of Mount St. Helens clouded the Pacific Northwest prompted a trove of research for some PNNL scientists.

Clouds in the eastern North Atlantic region will come under scrutiny from a bevy of airplane-based instruments this summer as scientists analyze the physical and chemical properties of clouds and aerosols.

Antonino Tumeo, a computational science researcher at PNNL, has been elevated to the rank of senior member in two professional societies.

Man-made pollution in eastern China's cities worsens when less dust blows in from the Gobi Desert, according to a new study in Nature Communications.

Organic matter found in vast quantities in oxygen-starved floodplains would yield only minimal energy for hungry microorganisms, which spurn the meal, researchers show in a study in Nature Geoscience.

Small particles of pollution and dust make clouds brighter, and now scientists have figured out a way to better use data to improve our understanding of how this process affects the planet's climate.

High concentrations of tiny pollution particles can invigorate cloud formation and boost snowfall on mountains, according to a new study.

High performance computing researcher Shuaiwen Leon Song asked if hardware called 3D stacked memory could do something it was never designed to do — help render 3D graphics.

A new window on the Arctic region is opening up, thanks to a new unmanned aerial system that has taken to the skies.

When water comes in for a landing on the common catalyst titanium oxide, it splits into hydroxyls just under half the time. Water's oxygen and hydrogen atoms shift back and forth between existing as water or hydroxyls, and water has the sli
