Cloud and atmospheric physics

Cloud and Atmospheric Physics

Our cloud and atmospheric physics group can offer research opportunities in both fundamental science and industrial applications. Dr. Gerald Wilemsky theoretically investigates the microphysics of aerosol particles and the kinetics of phase transitions. Current focus areas include binary homogeneous nucleation and droplet growth, the compositional structure of binary nanodroplets, homogeneous aerosol formation in supersonic gas expansions, particle nucleation and growth in supercritical fluids. Dr. Barbara Hale studies statistical mechanics and molecular modeling of atmospheric microphysics involving water and ice nucleation. Present work focuses on scaled models for nucleation and Monte Carlo computer simulations of small cluster energies of formation which demonstrate scaling phenomena.

Dr. Don Hagen is a founding member of the Missouri S&T Center of Excellence for Aerospace Particulate Emissions Reduction Research (COE). The Center studies particulate matter emissions in and near the airports and has developed a sampling methodology and associated mobile diagnostic facility optimized for exhaust characterization and particulate matter sampling using extractive sampling techniques. The Center activities are funded by a large number of industrial partners and government agencies. The Missouri S&T COE along with its collaborative research partners has received several national awards, as well as contributed to the Intergovernmental Panel on Climate Change (IPCC) assessment of the connection between the human activities and the global climate change. This work earned IPCC a share of the Nobel prize.


Studies the emission characteristics of aircraft engines on site with a combination of sophisticated recording devices complemented by computer monitoring. He and colleague professor Phil Whitfield from the chemistry department were lead researchers that helped the Intergovernmental Panel on Climate Change (IPCC) win the 2007 Nobel Peace Prize.

Dr. Hale studies cloud formation physics and has an interest in elementary particles.


Complements the research program with studies of complex systems, with a focus on thermodynamic properties.
