The Jaffe Group (specifically, Dan and Dee Ann) along with Andrew C. Schuerger of the University of Florida, Space Life Sciences Lab, organized a NASA-funded workshop in Bend, Oregon, at the beginning of May. This workshop gathered researchers from several universities and agencies to discuss a future experiment in “Aerobiology.” This is the study of the transport and biology of microbes in the atmosphere. Researchers plan to use Mt. Bachelor as a key sampling location to study the long-range transport of microbes in the global atmosphere. David Smith, now at NASA Ames Research Center, was one of the workshop participants. He is a UW alum (PhD Biology) and previously did ground-breaking work on aerobiology at Mt. Bachelor Observatory (see publications in 2011-2013).
In addition to PI Andrew Schuerger, David Smith, and Dan Jaffe, other participants were Co-PI Dale W. Griffin (US Geological Survey), Susannah M. Burrows (Pacific Northwest National Laboratory), Brent C. Christner (University of Florida), Cristina Gonzalez-Martin (University of La Laguna, Tenerife, Spain), Erin K. Lipp (University of Georgia), David G. Schmale (Virginia Tech), Boris Wawrik (University of Oklahoma), and Hongbin Yu (University of Maryland and NASA Goddard Space Flight Center).
Look for a future project studying microbes in the sky!
2016 was a record year for papers for the Jaffe Group. This year, group members were first authors of 5 papers and contributing authors of 11 more papers, for a total of 16 papers.
The following are the group’s first-authored papers of 2016:
Pao Baylon et al., Interannual variability in baseline ozone and its relationship to surface ozone in the western U.S.
Nicole Briggs et al., Particulate matter, ozone, and nitrogen species in aged wildfire plumes observed at the Mount Bachelor Observatory
Lynne Gratz et al., Airborne observations of mercury emissions from the Chicago/Gary urban/industrial area during the 2013 NOMADSS campaign
James Laing et al., Physical and optical properties of aged biomass burning aerosol from wildfires in Siberia and the Western USA at the Mt. Bachelor Observatory
Crystal McClure et al., Carbon dioxide in the free troposphere and boundary layer at the Mt. Bachelor Observatory
See the Publications page for a full list of our published papers.
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.
