Welcome to the Pratt Lab blog! Dr. Kerri Pratt is an assistant professor in the Departments of Chemistry and Earth & Environmental Sciences and faculty associate of the Program in the Environment at the University of Michigan. We study the chemical interactions of atmospheric trace gases, particles, clouds, and snow, with a focus on the Polar Regions and wintertime environments. Our interdisciplinary research has relevance to climate change, air quality, and human health. As an analytical chemistry lab, we primarily apply novel mass spectrometry techniques to our field research. We invite you to follow our adventures in (and outside!) the lab!

Pratt Lab attends the 2016 American Geophysical Union Fall Meeting

Prof. Kerri Pratt and post-docs Dr. Peter Peterson and Dr. Katheryn Kolesar, along with Ph.D. students Matt Gunsch, Rachel Kirpes, and Stephen McNamara, presented their results from a number of different Arctic research projects currently ongoing in the group! The 2016 Fall Meeting was a week-long conference in San Francisco (Dec 12-16, 2016) that attracted tens of thousands of scientists in earth science-related fields to share their work and engage in productive discussions. It was also a great opportunity to network and touch base with many of our collaborators!

The following presentations were given by Pratt Lab members:

Prof. Kerri Pratt: The poster "Influences on Summertime Arctic Aerosol Chemical Mixing States" highlighted work by Rachel Kirpes and Matt Gunsch. Prof. Pratt also co-organized the "Chemical Exchange Between the Air, Snow, and Ice: From the Micro to the Global Scale" Cryosphere session.

Dr. Peter Peterson: The oral presentation "Airborne Observations of Reactive Bromine Transport in the Arctic" featured airborne reactive bromine and particle measurements collected during the BROMEX 2012 study near Utqiagvik (Barrow), AK.

 Dr. Katheryn Kolesar: The oral presentation "Prudhoe Bay Emissions Drive Particle Growth Events Observed in Utqiagvik (Barrow), AK" highlighted our recently published analysis of years of aerosol data that show evidence of influence by the oil fields at Prudhoe Bay upwind from Utqiagvik (Barrow), AK.

Matt Gunsch: The poster presentation "Chemical Characterization of Atmospheric Particulate Matter from Prudhoe Bay, Alaska" featured results from our 2016 summer field study in the Prudhoe Bay oil fields of Alaska's North Slope.

Rachel Kirpes: The poster "The Chemical Composition and Mixing State of Sea Spray Aerosol and Organic Aerosol in the Winter-Spring Arctic" examined particles collected on recent Arctic field studies for their unique chemical characteristics to aid our understanding of their effects on radiative forcing and cloud formation.

Stephen McNamara: The poster "The Influence of Nitrogen Oxides on Chlorine Chemistry in Utqiagvik (Barrow), Alaska" presented results from our 2016 winter-spring field study at Utqiagvik (Barrow) in which high amounts of chlorine species were observed episodically using chemical ionization mass spectrometry.
