Project description
In this project I will study a group of very fast reacting gases in the atmosphere, the sesquiterpenes. They are emitted by boreal trees and I want to know what happens to them in the atmosphere, as well as, their importance for the air chemistry and the formation and growth of aerosol particles. Therefore, I will measure how much sesquiterpenes the whole forest (soil, understory and trees) emits. This will tell us the regional impact of these emissions. Additionally I will measure concentrations of the individual sesquiterpenes and other reactive gases in the forest air. From these measurements I can calculate how important sesquiterpenes are for the atmospheric chemistry. In a second step I will measure the reaction rates of individual sesquiterpenes and oxidize them in a chamber, which shows us the oxidation products of the individual sesquiterpenes and their potential to form and grow aerosols.
