Academic Profile


Tropospheric particles play an important role in many scientific areas, from air quality and chemical processes of atmospheric gases and aerosols to cloud formation and precipitation and climate change.

The processes involved are highly complex and require expertise in various fields such as aerosol and cloud physics, precipitation, remote sensing, fluid dynamics, meteorology in general and atmospheric chemistry.

The aim of this graduate school is to combine this expertise from partners at the University of Leipzig and the Leibniz Institute for Tropospheric Research in order to offer PhD students an interdisciplinary teaching and research environment focused on a common scientific field, namely a better understanding of physical and chemical processes in the field of clouds, aerosols and their radiation properties and effects.

Academic Aims

The Leibniz Institute for Tropospheric Research together with the Leipzig Institute for Meteorology, the Wilhelm-Ostwald-Institute for Physical and Theoretical Chemistry and the Institute of Analytical Chemistry offer a unique research and teaching environment covering all aspects of observation and modelling physical and chemical processes of aerosol and cloud particles in the Earth's atmosphere.

A wide range of chemical and physical laboratories and field-based research infrastructures and campaign activities exist where nearly all scientific questions concerning the development, processing, transport, cloud interaction of tropospheric aerosol particles as well as their effect on weather and climate can be addressed.

The contributing institutions have a world-leading reputation for carrying out large national and international field campaigns on land, air and sea. Modelling capabilities cover all scales from molecular reaction paths to regional aerosol-cloud interaction to global assessments of the role of aerosols on climate and climate change. Ground-based remote sensing resolves the vertical structure of aerosols and aerosol-cloud interaction at a variety of world-wide distributed stations. Satellite remote sensing provides spatio-temporal variability of aerosols, clouds, aerosol-cloud interaction as well as their radiative effects.

Currently, eight professorships ensure a unique academic supervision in the fields of atmospheric chemistry, physics, and modelling.
