Aerobiology workshop organized by Jaffe Group

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!

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.
