Research Interests

Dan Cziczo is an atmospheric chemist interested in the interrelationship of particulate matter and cloud formation. His research utilizes laboratory and field studies to elucidate how small particles interact with water vapor to form droplets and ice crystals which are important players in the Earth’s climate system. His group uses small cloud chambers in the laboratory to mimic atmospheric conditions that lead to cloud formation and observing clouds in situ from remote mountaintop sites or through the use of research aircraft. Dan’s current research interests include the chemical composition of atmospheric aerosols, Earth's radiative budget, and meteoritic, spacecraft debris and launch vehicle emissions in the atmosphere.
