 Airborne Research : Jaffe Group presents 5 papers at AGU
Posted on 2015/3/10 12:40:00

At the American Geophysical Union (AGU) meeting in December 2014, Jesse Ambrose, Lynne Gratz and Dan Jaffe gave presentations on the NOMADSS (Nitrogen, Oxidants, Mercury, and Aerosol Distributions, Sources, and Sinks) study.

- Observations and Model Analysis of Enhanced Oxidized Mercury in the Free Troposphere During NOMADSS by Lynne Gratz
- A Comparison of Inventoried and Measured U.S. Urban/Industrial Hg Emission Factors during the NOMADSS Experiment by Jesse Ambrose
- Aircraft Observations of Mercury over the US: The NOMADSS Experiment by Dan Jaffe

The NOMADSS study gathered airborne measurements of mercury in the eastern US during the summer of 2013.

Dan Jaffe also gave two other presentations at the meeting:
Crowdfunding: Right for Me? and Ozone from Wildfires: Peering through the Smog

The figure below, from Jesse Ambrose's presentation, shows measurements from three NOMADSS research flights. The numbered total mercury (THg), nitrogen oxide (NOx) and sulfur dioxide (SO2) plumes shown in the figure were attributed to coal-fired power plants.

 Mt. Bachelor Observatory : New paper analyzes mercury data from high-elevation sites
Posted on 2015/3/5 11:40:00

A new paper published in Atmospheric Chemistry and Physics uses a global model to understand atmospheric mercury (Hg) at five high-elevation sites. This paper, written by Jaffe Group alumnus Peter Weiss-Penzias along with Dan Jaffe and several other coauthors, analyzed data from Mt. Bachelor Observatory, three other sites in the western US, and one site in Taiwan. They used a model "to help interpret the spatio-temporal trends in, and relationships among, the Hg species and ancillary parameters, to understand better the sources and fate of atmospheric RM [reactive mercury]."

 Group News : New paper explores pollution in Chinese nature reserve
Posted on 2014/12/23 12:30:53

In the last 20 years, profound ecological changes including tree dieback have been observed in Jiuzhaigou National Nature Reserve, Sichuan Province, China. A new paper published in Science of the Total Environment investigated the deposition of sulfur and nitrogen, which may contribute to the negative changes in this sensitive region.

Dan Jaffe, in collaboration with the paper's lead author, Xue Qiao of Sichuan University, Chengdu, China, assisted with setting up the acid rain sampling devices in the nature reserve and analyzing the data. The Jaffe Group continues to collaborate with this group at Sichuan University.

 Group News : Dan Jaffe on Science Friday radio broadcast
Posted on 2014/11/18 12:00:00

Science Friday featured Dan Jaffe as one of the guests on its November 14 radio broadcast. The segment, "Lacking Funding, Some Scientists Turn to the Crowd," highlighted the case for nontraditional funding for scientific research. Dan discussed his experience with crowdsourced funding of coal train research in Washington State.

 Group News : Jaffe Group welcomes visiting Chinese scientist
Posted on 2014/11/13 14:48:25

We are honored to host Dr. Lei Zhang, a visiting scholar from Beijing, China! Lei, a postdoctoral fellow at the School of the Environment at Tsinghua University, will be joining the Jaffe Group until the middle of January. He will be working with group member Crystal McClure on methods for identifying and quantifying speciated GOM (gaseous oxidized mercury), both in flue gas and in ambient air. This area is on the frontier of mercury research and supports the cooperation between the Jaffe Group and Prof. Shuxiao Wang's group at Tsinghua University.

Lei expressed his excitement to be in the Seattle area and working with the Jaffe Group: "It is my first time here in Seattle. I love this city. It is full of innovation, Microsoft, Boeing, Amazon and even Starbucks. I am grateful to have the opportunity to spend 3 months with this cutting-edge research group, and hope my stay in UW-Bothell can yield progress in the research works of both myself and Jaffe's group."
