Curriculum Vitae (pdf format, updated December 28, 2004)

Research Interests:  Modeling the chemistry in and around clouds

• Chemistry in and around deep convection
• Numerical Simulations of the July 10 Stratospheric-Tropospheric Experiment: Radiation, Aerosols, and Ozone/Deep Convection storm: Redistribution of Soluble Tracers describes the redistribution of tracers that have the same initial concentration profile but have different solubitiies using a 3-dimensional convective cloud model. (Last updated February 2004)
• Chemistry in a large eddy simulation
• Aqueous chemistry in the regional chemistry transport model
• The Effect of Marine Boundary Layer Clouds on Tropospheric Chemistry as Analyzed in a Regional Chemistry Transport Model describes results from HANK simulations that included aqueous chemistry. These simulations over the Pacific Basin show that aqueous chemistry coupled with the radiative effect of clouds on photolysis rates can reduce ozone concentrations by 320 pptv per day in the marine boundary layer. (Last updated December 4, 2001)
• Chemistry will soon be implemented within the Weather and Research Forecast (WRF) Model . To produce a community assessment of approaches and methodologies, a workshop on modeling chemistry in cloud and mesoscale models was held 6-8 March 2000 in Boulder, Colorado. This link describes the topics presented at the workshop and summarizes the discussion.
• Global sulfur model
