Terpenes (isoprene, monoterpenes and sesquiterpenes) are biogenic volatile organic compounds (BVOC) emitted from plants with an important impact on chemical reactions in the atmosphere. BVOCs interact with oxidants like e.g. ozone on very short time scales due to their reactivity, and reaction products might form secondary organic aerosols (SOA), having a major impact on cloud forming processes and radiation transfer. The aim of this project is to analyze the variability and seasonality of BVOC emissions (with a focus on sesquiterpenes) from a Swedish boreal forest and to determine the environmental drivers involved. The work will contribute to a better understanding of BVOC emission variability and quantify its role in atmospheric chemistry, i.e. plant stress caused by oxidants. We seek an enthusiastic PhD student for field measurements to quantify sesquiterpene emission strength and pattern for a boreal forest, and to analyze in-canopy chemistry.
Highest priority will be given to applicants with a M.Sc. degree (or equivalent) in a quantitative environmental sciences discipline, for instance meteorology, physical geography, environmental physics, environmental engineering, biogeochemistry. Applications from candidates who are close to completion of their undergraduate studies will also be considered.
Application deadline is 2012-04-18.
