A Steeply Rising Tail

Full Project Title: A Steeply Rising Tail: Quantifying the Absorption of Organic Aerosols in the Near-Ultraviolet

Funding Body: Science Foundation Ireland

Project type: PhD, MSc student

Period:  October 2011 – September 2015

Researcher: Eoin Wilson, Donovan Fullam

Project Description

This project will use a unique broadband optical cavity spectrometer to quantify the near-ultraviolet extinction of secondary organic aerosols (SOA) generated in an atmosphere simulation chamber. Scattering will be quantified using a nephelometer, thereby providing the information needed to quantify aerosol absorption. These tools will be exploited to investigate the dependence of aerosol optical properties on the organic precursor, oxidising conditions, and presence of seed aerosols, and how these optical properties evolve over several hours. Volatile organic precursors to be studied include major biogenic sources (such as the terpenes) as well as anthropogenic precursors like toluene.
