How will our world respond to climate change? In our research group, we study the relationship between the atmosphere and the terrestrial biosphere.
Why do we study the terrestrial biosphere? Trees are a living, breathing dynamic component of the Earth system. Like humans, they can respond and adapt to climate change in ways that we cannot anticipate. Further, these responses can influence atmospheric composition through the release of gas phase compounds like water vapor and volatile organic compounds (VOC), and particulate matter such as pollen. These gas and aerosol components can cause changes in climate at the local and regional scale by altering surface air temperatures and precipitation.
How can we represent such a dynamic, responsive component such as trees into our climate models? And how important are these natural changes in comparison to those that are driven by human beings? Our research group works to integrate the dynamic biosphere into high-resolution models and compare with observations, with the ultimate goal of developing a comprehensive understanding of regional scale climate and atmospheric chemistry.
A new College of Engineering Multidisciplinary Design program is launching this term that will work to advance modeling the Great Lakes system as described here . This two-year project is driven by student projects, so stay tuned for new results!
Presentations from the group at the 2015 AMS Meeting include:
- Sunday, January 4: Meteorological variability and the observed aerosol first indirect effect over the Southern Great Plains (REU student Samuel Pennypacker)
- Wednesday, January 7: Investigating the impacts of dust and anthropogenic emission on indirect aerosol effects in convective clouds in the Southern Great Plains (Ph.D. student Stacey Kawecki)
- Wednesday, January 7: Projected precipitation changes within the Great Lakes region: A multi-scale analysis of precipitation intensity and seasonality (Master's student Samantha Basile)December 2014
Congratulations to Ph.D. student Susan Cheng on the acceptance of her first paper in Agricultural and Forest Meteorology . It uses AmeriFlux data to quantify the role of diffuse light on carbon updake.
Former Ph.D. student Alex Bryan's manuscript is now online at JGR-Atmospheres, titled "Regional modeling of surface-atmosphere interactions and their impact on Great Lakes hydroclimate"
Presentations from the group at the 2014 AGU Fall Meeting include:
- Monday December 15: H13C-1129: Regional modeling of surface-atmosphere interactions and their impact on Great Lakes hydroclimate (former Ph.D. student Alex Bryan)

Congratulations to Yang Li who was awarded an NCAR Graduate Visitor fellowship! She will visit Boulder next summer to work with Mary Barth on LES modeling with chemistry.
November 14: Grad students Stacey Kawecki and Yang Li present posters on recent research at the UM Engineering Graduate Symposium.October 2014
October 20: Dr. Steiner presents at the NC State Marine, Earth and Atmospheric Sciences department seminar.
October 9: SNRE postdoc Zhiyuan Song presents a poster at the UM MCubed symposium titled "Dynamics of rural community forest use and labor migration in developing countries."September 2014
Postdoc Kirsti Ashworth publishes a News and Views piece in Nature Climate Change titled Atmospheric chemistry: A new player in climate change.
September 29: Dr. Steiner presents recent work on pollen phenological modeling at International Congress of Biometeorology in Cleveland, OH.
We're changing up the format for AOSS 747 (Graduate Student Seminar) this term - students will be writing a research proposal and working on professional development. Contact Dr. Steiner if you are interested!
Group meetings for the semester will be held on Thursdays from 2-3PM in SRB 2218. All interested students are welcome to attend.
