Chemical Imaging of Atmospheric Organic Particles

13 July 2015 - 31 March 2018

Lead Scientist: Alexander Laskin

Observatory: SGP

The goal of this project is to characterize the chemical and physical properties of atmospheric particles to establish quantitative a relationship between the composition of aerosol particle and their atmospheric impacts. The specific research efforts will be focused on in-depth microscopy studies of chemical and physical properties of atmospheric organic particles collected at the SGP field site. An array of novel molecular-level characterization and chemical imaging approaches will be used to characterize chemical composition of particles and elucidate fundamental processes governing their atmospheric aging, evolution of chemical composition, optical properties, cloud formation ability, and implications for particle-cloud interactions – the most challenging problems relevant to predictive understanding of aerosol effects on climate.
