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.
Graduate student Matthew Wozniak sets up the miniMPL at the University of Michigan Biological Station (UMBS) ... we're hoping to see some pollen plumes soon!
Graduate student Stacey Kawecki and undergraduate group member Peiyun Zhang present posters at the Michigan Geophysical Union on April 7.March 2016
Graduate student Yang Li is awarded the Barbour Scholarship from the Rackham Graduate School. This fellowship recognizes outstanding students from the Orient. Congratulations Yang!
Graduate student Yang Li travels to NCAR in March for a follow-up visit from the Visiting Student Program last summer working on LES modeling with Mary Barth.
Dr. Steiner travels to India for 36 hours! Yes, it's true... but it was worth the trip to attend the iLEAPS Scientific Steering Committee meeting in Chandighar, India, hosted by Vinayak Sinha at the IISER Mohali.February 2016
