2 New papers published in October

Two Jaffe Group members have published peer-reviewed papers in October. Well done to Xi Gong and Pao Baylon for their outstanding work!

Xi Gong and her coauthors used a statistical approach, the Generalized Additive Model,  to quantify ozone impacts from wildfires on 8 US cities. They showed that this approach can provide quantitative support for situations when large contributions from noncontrollable sources, such as wildfires, caused an exceedance of the EPA’s daily ozone standard.

Pao Baylon and his coauthors looked at a Siberian biomass burning event in Spring 2015 that was observed at Mt. Bachelor Observatory and by satellite instruments, and also intercepted by a research aircraft. When the plume was in the eastern Pacific, it split into two plumes, one moving eastward toward MBO and the other moving northeast to Alaska and then south to the US Midwest. The second plume was observed by the aircraft in the Midwest. Baylon et al. found that the ozone production observed at MBO was higher than that of the aircraft plume. This was due to the plume at MBO being warmer and the aircraft plume being colder.

Ambrose publishes paper on new instrument for measurements of hydrogen cyanide

On June 1, Dr. Jesse Ambrose and colleagues published a paper in the journal Atmospheric Measurement Techniques that describes a new instrument for measurements of hydrogen cyanide (HCN), a selective tracer of biomass burning emissions, in the lower atmosphere. The instrument is capable of providing long-term HCN measurements in the background atmosphere and will serve as a valuable research tool for assessing the influence of wildfire and domestic wood burning smoke on atmospheric chemistry and air quality.
