    Yun Qian Directed International UQ Workshop

    Dr. Yun Qian, atmospheric and climate modeling scientist at PNNL organized and directed an international workshop on “Uncertainty Quantification in Climate Modeling and Projection” in Trieste, Italy. Drawing on international interest nearly 70 scientists and students from some 30 countries around the world attended the five-day workshop at the Abdus Salam International Centre for Theoretical Physics (ICTP) in mid-July 2015.

    Hagos Contributes to State of the Climate Report

    Dr. Samson Hagos, atmospheric scientist at Pacific Northwest National Laboratory, led a regional climate study that was included in the international report State of the Climate in 2014. This report was featured in Bulletin of the American Meteorological Society.

  • Dr. Katherine Calvin

    Katherine Calvin Honored for Early Career Exceptional Achievement

    Congratulations to Dr. Katherine Calvin who received a 2015 Ronald L. Brodzinski Early Career Exceptional Achievement award for leadership in research that integrates environmental and climate change research and their socioeconomic implications for the future. Calvin and other Science and Engineering Achievement awardees will be recognized at PNNL’s Pathway to Excellence Award Banquet in September.

    Six Parameters Influence Modeling Precipitation

    Researchers at PNNL systematically identified six modeling parameters that have the greatest influence on modeling global precipitation. They found that the influence of individual parameters does not depend on sampling approach or the associated parameters. By using Uncertainty Quantification (UQ) tools they showed that the precipitation variance is due to contributions from individual parameters most of the time.

  • Rasch and Guenther

    Rasch and Guenther Elected Fellows of AGU

    Congratulations to Drs. Phil Rasch and Alex Guenther of PNNL, as they attain the elite rank of scientists elected as Fellows of the American Geophysical Union. The honor is bestowed for “exceptional scientific contributions and attained acknowledged eminence in the fields of earth and space science” and is given to no more than one-tenth of one percent of all members of the organization.

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.
