Research

We study everything related to atmospheric transport: 
Aerosol transport, greenhouse gas transport, heat transport, microplastic transport, and moisture transport. Our main tool is the Lagrangian particle dispersion model FLEXPART, which is also actively developed in the group.

We aim to address the following research topics:

Aerosols

• Interpretations of aerosol data from observational campaigns: which are the main sources and time of transport?
• How does the shape of particles affect the gravitational settling and their lifetime in the atmosphere? How is the atmospheric transport of non-spherical particles (e.g. volcanic ashes, dust particles, microplastic)?
• Which are the main sources of microplastic in the atmosphere, and which are their emission rates?

Greenhouse Gases

• What is the contribution of different countries to observed GHG concentrations?
• What does the global and regional spatio-temporal emission distribution of certain GHG species look like?
• How can we improve the method of atmospheric inverse modeling?

Energy and Moisture Transport in the Atmosphere

• What is the impact of atmospheric transport on global and regional climate extreme events?
• Can we make objective Lagrangian definitions of circulation patterns with the help of a Lagrangian reanalysis?
• How long does moisture reside in the atmosphere?

Paleoclimate

• Where are the source regions of moisture/dust archived in ice cores?
• What influences the climate proxy signal in ice cores and other paleoarchives?

Lagrangian Modeling

• How can we adapt FLEXPART to be able to run easily with input data from other models, e.g. CMIP6 models (CESM)?
• How can we develop FLEXPARTiso?
• Should we develop an online version of FLEXPART for a specific model, e.g. ICON / CESM?
