  • West Africa Dust

    Dust Increases Cloud Cover

    Surprisingly, cloud cover increases when more dust blows off the west coast of Africa, according to a 150-year-long global climate simulation run by researchers from the University of California San Diego and Pacific Northwest National Laboratory. By simulating the effects of dust over North Africa without the effects of emissions from human activity, such as coal-burning power plants, the scientists isolated a view of this natural event to understand the full impact of dust as it influences cloud formation.

  • Dr. Evgueni Kassianov

    Kassianov Brings Climate Physics Expertise to Atmosphere Editorial Board

    Congratulations to Dr. Evgueni Kassianov, atmospheric scientist at Pacific Northwest National Laboratory, who was appointed to the Editorial Advisory Board of Atmosphere. As a board member, he will use his research expertise in remote sensing of clouds, aerosols, and land surface to evaluate manuscripts submitted for publishing as well as edit a special issue on a topic related to his research interests.

    Five PNNL Researchers Named Most Cited

    Five researchers at Pacific Northwest National Laboratory have been named to a comprehensive list of the world's most referenced scientists. The list includes more than 3,200 researchers whose scientific reports were in the top 1 percent of papers receiving the most references. The five scientists are Jun Liu, Alex Guenther, Phil Rasch, Yuyan Shao and Yuehe Lin.

    Predicting Atmospheric Particle Population's Weight Gain

    Even particles in the atmosphere can gain weight. The culprit is newly formed carbon-containing compounds in the atmosphere, also referred to as secondary organic aerosols (SOAs) that pile on pre-existing particles for a gain in mass. To address the size-dependent "weight" gain problem, researchers, led by Dr. Rahul Zaveri of PNNL, designed a new modeling framework that is a significant advancement over the previous modeling paradigm that focused only on the total mass.

  • SALVI technology

    Window into Liquid Analysis Earns PNNL an R&D 100 Award

    Many studies rely on knowing precisely how solids and liquids interact on a molecular level, but liquids evaporate in the vacuum of certain powerful scientific instruments. PNNL developed SALVI, or the System for Analysis at the Liquid Vacuum Interface, that for the first time allows these instruments to image liquid samples in real time. R&D Magazine honored SALVI’s research team with a 2014 R&D 100 award. The magazine selects the 100 most innovative scientific and technological breakthroughs of the year.

How do human activities and natural systems interact to affect the Earth's climate? Ultimately, that is the question challenging scientists in PNNL’s Atmospheric Sciences & Global Change Division.
