Impact of Ship Emissions Reductions

Pollutant emissions from shipping affect air quality in coastal cities. The strong reduction in sulfur emissions in 2020 is expected to have contributed to the recent acceleration in global warming. However, the magnitude of this (aerosol radiative) effect is highly uncertain. You will use our state-of-the-art atmospheric chemistry model in MESSy, running on our supercomputer, to investigate the impact of sulfur on aerosols, clouds and the Earth’s energy imbalance.

Impact of CO₂ Direct Air Capture

Removing CO₂ from the atmosphere through direct air capture will be important in the energy transition. You will measure and quantify unintended emissions associated with this technology. These can have unwanted air quality and climate side-effects that need to be quantified in order to improve the process. Measurements will be carried out in test facilities using gas chromatography and spectroscopic instruments.

Effect of Dust on Climate Change

Minerals from deserts such as the Sahara influence climate change by scattering and absorbing sunlight. The overall past, present and future effects are uncertain. You will analyse results from global chemical transport models that simulate changes in dust emissions. You will develop the tools needed to quantify the impact of dust on global warming for assessment reports such as the IPCC report.

Source Apportionment of Pollutants

Organic pollutants were measured using mass spectrometer instrument during a year-long measurement campaign, in which ambient air was flowed through our SAPHIR simulation chamber. You will analyse the complex mass spectrum to attribute pollutant sources by using state-of-the-art statistical methods. The aim is to study the different effects of biogenic and anthropogenic sources.

Atmospheric Chemical Reactions and Structure Activity Relationship

Structure-activity relationship (SAR) can be used to determine the rate constants of chemical reactions for which there are no measurements. You will evaluate the performance of SAR for a range of atmospheric reactions to determine the applicability of SAR. This will involve literature studies, the use of statistical approaches and the programming of tools for the analysis.

Improving Air Quality Predictions

Regional air quality prediction is carried out by the operational model EURAD-IM. An important asset of EURAD-IM is the assimilation of measurements from monitoring stations. You will contribute to the improvement of the predictions by implementing new features in the model and evaluating the performance in simulation studies using real data.

New Instruments for Air Pollutants

The low atmospheric concentrations of short-lived pollutants require highly sensitive instruments that are not commercially available. You will develop a new method for the detection of nitrogen oxide species using state-of-the-art laser spectroscopy and test and validate the performance of the instrument in experiments in our SAPHIR chamber and / or in field experiments.

Mass Spectrometry Methods

Simulation chambers are an important tool for understanding atmospheric processes, in particular the formation of particles from gas phase precursors. We use the latest generation of chemical ionisation mass spectrometers and ionisation methods. You will support these measurements by developing and characterising new calibration methods and applying them in our chamber campaigns.
