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.
Our new laboratory study on pollen as cloud condensation nucelei is now online in Geophysical Research Letters. More information about the article is discussed in this video, with media coverage by AGU, Newsweek, and CBSNews.
A new review paper on ozone-temperature relationships, co-authored with Sally Pusede and Ron Cohen, is now online in Chemical Reviews.
