Changes in the modern environment are widely acknowledged as one of the key issues of the 21st century. Natural variability and human-caused alterations in atmospheric and land-surface properties continue to alter energetic and moisture balances of the Earth, thereby causing climate change. Among these alterations are increases in greenhouse gas concentrations that lead to associated changes in temperature and precipitation patterns. Research and instruction within the Climate and Environmental Change Program at Indiana University seeks to better understand these atmospheric-environmental processes and their impacts on natural ecosystems and human society. As such, the Department of Geography has developed research themes that span the entire range of scales – faculty actively do research at the global-, synoptic-, meso-, and micro-scales.

The Climate and Environmental Change faculty and students who conduct experimental work are housed in the new Multidisciplinary Science Building II (MSB-II). There is extensive laboratory space dedicated to facilitate development, operation and testing of instruments. For field studies, we have an extensive collection of state of the art meteorological instrumentation, including a variety of instruments that focus on atmosphere-biosphere interaction. The department also maintains an instrumented research tower and associated labs as part of the AmeriFlux network, which provides access to state-of-art research projects and instrumentation.

Indiana University regularly is ranked among the top US institutions for technology resources, including network connectivity, lab resources, and high-performance computing. This infrastructure provides students and faculty working in atmospheric science with an excellent environment for their research and teaching activities. Graduate students and advanced undergraduates can expect to participate in faculty research projects funded by EPA, NASA, NOAA, NSF, and DOE. A key component of our program is the close interaction of students with faculty members in independent research and readings courses in their areas of interest.
