IMK-AAF Organisational Structure

IMK-AAF is organised in groups, whose specific working areas are:

 

Aerosol-Cloud-Processes

Head: Dr. Ottmar Möhler

This group investigates aerosol-cloud-processes, in particular primary ice formation in atmospheric clouds using the AIDA facility, and develops parameterisations of these processes for use in atmospheric cloud, weather and climate models. We also develop new methods and instruments to measure and characterise ice nucleating particles both in laboratory and field projects.

 

Aerosol Chemistry and Air Quality

Head: Dr. Harald Saathoff

We characterise complex aerosol systems like SOA or combustion emissions regarding their chemical and physical properties relevant for climate, weather and air quality. Field studies focus on urban aerosols and process studies in the AIDA chamber on aerosol formation and aging.

 

Aerosol and Cloud Particle Optics

Head: Dr. Martin Schnaiter

The group investigates the interaction of ultraviolet and visible light with atmospheric aerosol and cloud particles in order to (i) measure their shortwave spectral optical properties, (ii) deduce the bioaerosol content, and (iii) study the structural details of ice particles. We develop optical instrumentation that is deployed in aircraft missions, mountain top studies, and cloud chamber experiments.

 

Cloud Microphysics

Head: Dr. Alexei Kiselev

The group investigates microphysical cloud processes like the nucleation of liquid water and ice, droplet collisions and fragmentation and secondary ice processes in laboratory experiments. The main tools are single droplet electrodynamic balances, cold stages, particle traps, mass spectrometry, nonlinear optics and environmental scanning electron microscopy.

 

Engineering and Infrastructure

Head: Georg Scheurig

The “Engineering and Infrastructure“ group provides the technical support for construction, engineering mechanics, and electronics. Members of the group also are taking care of the servicing of IMK-AAF’s facilities and buildings.
