We are a research group in the department of Chemistry and CIRES at the University of Colorado at Boulder. Our research is aimed at contributing to a better understanding of the Earth's complex atmosphere. Specifically, work in our group specializes in understanding atmospheric heterogeneous chemistry. For example, the importance of heterogeneous chemistry in catalyzing stratospheric ozone loss has been firmly established. In the case of the ozone hole, reactions on polar stratospheric clouds (PSCs) are responsible for repartitioning chlorine reservoir species into photochemically active species capable of catalytically destroying ozone. However, significant questions still remain as to the composition, phase, nucleation mechanisms, and surface chemistry of PSCs. Traditionally, work in our group has been aimed at answering these questions.
Today, the research in our group has expanded in an attempt to answer similar questions about cirrus clouds and other particulate matter that exist in the troposphere. Currently, our research explores the chemistry of tropospheric aerosols, and the impact of such aerosols on climate and visibility. Finally, we are also probing aerosols in other planetary atmospheres and studying the possible role of aerosols on early Earth as life was developing. Research in our group is funded primarily through NASA and NSF.
In the News
Recent Graduations Three Tolbert group members have graduated! Dr. Danielle Nuding has taken a position as a Systems Engineer at the Jet Propulsion Laboratory in Pasadena, CA. Dr. Nuding will be working on mission development for assigned JPL flight projects, which will include developing systems and mission level architectures. Dr. Gregg Schill was awarded a National Science Foundation Postdoctoral Research Fellowship and will be working with Prof. Paul DeMott at Colorado State University in Fort Collins, CO. Dr. Schill will be continuing ice nucleation studies, but on ambient aerosol from biomass burning and fossil fuel combustion. Dr. Kyle Zarzana will join Dr. Steve Brown's group at the NOAA Earth System Research Laboratory in Boulder, CO. Dr. Zarzana will be using cavity enhanced spectroscopy to study glyoxal and other traces gases.
