Organic matter and non-refractory aerosol over the remote Southeast Pacific Ocean : oceanic and combustion sources

Abstract

Studies of organic aerosol (OA) over the equatorial and southern oceans remain underrepresented relative to high and mid-latitudes. This constitutes a large gap in the understanding of OA production in marine systems. Here we present results from the Southeast and Central Pacific Ocean, areas where few aerosol measurements have been taken, in order to facilitate the understanding of global background aerosol. Results from three such experiments are discussed in this thesis and results are compared and contrasted to those from previous clean air investigations.
