The impact of aerosols on climate remains poorly constrained, leading to considerable uncertainties in predicting the climate sensitivity to greenhouse gases. A large fraction of these uncertainties is due to our deficient knowledge of the composition and magnitude of natural emissions before 1750, especially for organic aerosols, forming 20-70 % of today’s fine particulate matter.
You will determine the chemical composition and sources of organic aerosols in the pre-industrial and industrial atmosphere by analyzing molecular markers in ice cores from Europe and the Central Asian Altai, applying sensitive liquid chromatography coupled to electrospray ionization ultrahigh resolution mass spectrometry.
You hold a PhD degree in chemistry, environmental sciences, physics or a related field. You have a strong background in organic mass spectrometry. As a team player you enjoy working in an interdisciplinary, multinational research environment.
Our institution is based on an interdisciplinary, innovative and dynamic collaboration. You will profit from a systematic training on the job, in addition to personal development possibilities and our pronounced vocational training culture. If you wish to optimally combine work and family life or other personal interests, we are able to support you with our modern employment conditions and the on-site infrastructure.
Your employment contract is limited to 2 years.
