    New Method Detects How Ocean Biology Affects Sea Spray Chemistry

    PNNL and Los Alamos National Laboratory scientists devised a new method to identify the chemical composition of sea spray, and how that chemical make-up is affected by ocean biology. The new model provides a better description of microscopic sea organisms affecting ocean chemistry that in turn affects the chemistry of sea spray particles. The far-flung particles can loft high enough to affect cloud-forming droplets.

  • Dr. Xiao-Ying Yu and SALVI

    Team Wins Federal Excellence in Technology Transfer Award

    Research led by Dr. Xiao-Ying Yu, a scientist at Pacific Northwest National Laboratory and her team developed PNNL's System for Analysis at the Liquid Vacuum Interface, or SALVI, allowing—for the first time—imaging of liquid samples reacting in real-time and a realistic environment. They won a prestigious Excellence in Technology Transfer Award in 2015 from the Federal Laboratory Consortium for Technology Transfer (FLC).

  • L. Ruby Leung

    Leung and Kravitz Named Top Authors

    PNNLscientists representing both ends of the research experience spectrum were recognized for their publication prowess by the American Geophysical Union (AGU). Congratulations to Drs. L. Ruby Leung, a Laboratory Fellow, and Ben Kravitz, a postdoctoral researcher, both atmospheric scientists at PNNL. AGU named the two scientists among the top authors in American Geophysical Union journals over the last three years.

  • December 2014 cover of JGR Atmospheres

    Cloud Identification Research Featured on Journal Cover

    Congratulations to Dr. Matus N. Martini, a postdoctoral researcher in atmospheric sciences at Pacific Northwest National Laboratory, who led research that was featured on the November cover of the Journal of Geophysical Research: Atmospheres. Martini and his colleagues developed a new technique to identify marine clouds in a climate model.

  • dark particles coat Greenland ice sheet and promote melting

    Particle's Warming Impact Brought to Light

    When dust, soot and other black or dark-colored particles emitted through pollution are deposited in snow and ice, they increase melting. PNNL led a comprehensive, state-of-the-science review of light-absorbing particles. The findings offer insight on these complex climate-changers, underscoring the particles' far-reaching influence, affecting freshwater supplies and sea-level rise, as well as atmospheric heat and cloud formation.

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.
