On Tuesday, January 24, Jesse Ambrose will present an overview of air quality research within the Jaffe Research Group. Hosted by UW Bothell's Office of Research in an effort to promote and raise awareness about current and ongoing research, Research in Progress is a weekly seminar series held on campus, and is open to all interested students, faculty, staff, and members of the general public.

Please join us for refreshments and stimulating scientific discussion!

Time: Tuesday, January 24 @ 4 pm
Location: UW1-361 (UW Bothell campus)

In a recently published Nature Geoscience paper, Seth Lyman and Dan Jaffe report their findings with regards to the behavior of atmospheric mercury from their 2010 aircraft campaign over parts of North America and Europe. The data from this campaign significantly improve our understanding ofthe cycling of mercury in the atmosphere and how mercury can accumulate in ecosystems.

The full text of the paper can be found here.

Dan was invited to a national panel to summarize our understanding of Policy Relevant Background (PRB) ozone. PRB O3 refers to the concentration of ozone that blows in to the US from foreign sources and hence is not subject to domestic emission controls. Understanding PRB O3 is therefore essential for regulating ozone in the US. The report was strongly influenced by our work, including data from Mt. Bachelor.

The published paper summarizing the panel's findings can be found here.

2011 was a great year for the group; we published 11 papers in 2011.

Near the end of last year, Dr. Seth Lyman of the Jaffe Group partook in an very interesting and one-of-a-kind study regarding aircraft mercury measurements.

The objective of this research is to test a novel dual-channel aircraft instrument for measurement of gaseous elemental mercury (GEM) and reactive gaseous mercury (RGM) aboard the NSF/NCAR C-130 aircraft. Here, Seth gives some details on the project:
