<b class=""><span lang="EN-GB" class="" style="font-size: 11pt; font-family: Calibri, sans-serif;">Description:</span></b><span lang="EN-GB" class="" style="font-size: 11pt; font-family: Calibri, sans-serif;"> The aim of </span><span lang="EN-GB" class="" style="font-size: 11pt; font-family: Calibri, sans-serif; color: rgb(72, 72, 72);">this
project is to quantify, understand and provide tools to describe atmospheric oxidation of organic compounds. This oxidation is important to understand formation of secondary organic aerosol (SOA) but also the generally production of oxygenated compounds that
can effect air quality both in outdoor and indoor environments. Specifically, this project applies high resolution mass spectroscopy techniques for detailed analysis of gas and particle phase to elucidate chemical mechanisms of importance for atmospheric SOA.
A specific aim is how to link SOA mechanisms to model developments for descriptions in air quality and climate models.<o:p class=""></o:p></span></p>

<span lang="EN-GB" class="" style="font-size: 11pt; font-family: Calibri, sans-serif; color: rgb(72, 72, 72);">The experiments will primarily be conducted using our high-resolution time-of-flight chemical-ionization mass spectrometer in combination with inlets
separating particle and gas phase for characterization of organic compositions (see e.g. key publications below) . In addition to work in Sweden one is expected to participate in our international collaboration projects and might during limited time be relocated
abroad (ca weeks to a month). The work involves a great deal of analysis and evaluation of measurement data for the understanding and quantification of atmospheric oxidation of organic substances.<o:p class=""></o:p></span></p>
