Current climate-related research includes both basic research on climate change and impacts of climate change. With colleagues Arritt and Gutowski, I am co-PI on the North American Regional Climate Change Assessment Program. Research on climate-change impacts includes assessing the interactive roles of climate and land-manager choices on land-use/land-cover change in agricultural area, development and evaluation of downscaling tools for near-surface flow and impacts of climate change on wind power, evaluating effects of climate changes on Midwest agroecosystems using a climate-crop coupled model, and assessment of variability and trends in Iowa climate data on pavement performance by use of a mechanistic-empirical pavement design model.
