    Yu Invited to Join Advisory Group for Emergency Exposures

    Congratulations to Dr. Xiao-Ying Yu, a chemist at Pacific Northwest National Laboratory, who was appointed to the prestigious Temporary Emergency Exposure Limit (TEEL) Advisory Group. Yu was selected by Jose Rafael Berrios, Director of the U.S. Department of Energy's (DOE) Office of Emergency Management and Policy, for her accomplishments in applied toxicology anddevelopment of the chemical mixture methodology (CMM).

    PNNL Nabs #1 Particle Pushers

    New research led by Pacific Northwest National Laboratory shows,for the first time,that burning vegetation and bio-based fuel are the largest source of particle-making vapors in the atmosphere. The discovery translates to an order-of-magnitude change in the impact of secondary organic aerosols on the Earth's energy balance.

    Nighttime Lights Reveal Size of Urban Sprawl

    Using satellite data of nighttime light intensity, a research team led by PNNL developed a new method to map urbanization; that is, the increasing population concentration in urban areas. They built a globally consistent, time-sensitive, and updateable urban extent map from nightlights data gathered from satellites about 500 miles above the Earth.

  • Dr. Susannah Burrows

    Burrows Honored by DOE for Outstanding Contribution

    Congratulations to Dr. Susannah Burrows, atmospheric scientist at PNNL. She was recognized for her outstanding contribution to the Department of Energy's new advanced Earth system model called ACME. Burrows was one of two researchers to receive an award at a recent team meetingfrom Dr. Sharlene Weatherwax, the Associate Director of Science for the Office of Science's Biological and Environmental Research division.

    Volcanic Ash Proves Inefficient Cloud Ice Maker

    A 2010 Icelandic volcano's ash plume caused havoc for vacationers across Europe. But did it also dramatically change clouds? Researchers at PNNL found that volcanic ash is not as efficient as common dust in birthing cloud ice particles. Using a novel laboratory testing chamber they formed cloud ice, a process called ice nucleation, around particles of dust and volcanic ash. Their results revealed the importance of optimal particle structure to efficiently attract super cold water vapor to nucleate ice.

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.
