Abstract:

Aerosols, or particles, emitted into the air have adverse effects for regional air quality and health. In addition, aerosols significantly impact earth’s climate and the hydrological cycle. They can directly reflect the amount of incoming solar radiation into space; by acting as cloud condensation nuclei (CCN), they can indirectly impact climate by affecting cloud albedo. Our current assessment of the interactions of aerosols and clouds is uncertain and parameters used to estimate cloud droplet formation in global climate models are not well constrained. Understanding the chemical and thermodynamic properties that control the ability of particles to form droplets, CCN activity, and droplet growth are necessary for constraining impacts on particle transport, particle inhalation, the hydrological cycle and uncertainties from the aerosol indirect effect. In this presentation, we discuss and identify fundamental parameters that affect aerosol formation and droplet growth from unique sources and diverse environments.
