Aerosol Dynamics Simulations: Instrumentation and Behavior

Nanoparticles are produced in the atmosphere by nucleation. This research group has developed instruments that can measure the size distributions of such particles down to 1 nm. They are analyzing those data to determine nanoparticle growth rates, which determine the likelihood that a freshly nucleated particle will survive and affect global climate. The researchers are using MSI resources for simulations that determine the relationship between size-dependent growth rates and steady-state size distributions. They are also using MSI to improve their understanding of their measurements.
