Working Group "Aerosol and Reactive Tracer Modelling", Leader Dr. Ali Hoshyaripour
Our research advances the understanding of atmospheric aerosols and their interactions with clouds and radiation across scales. We investigate the physical and chemical mechanisms governing aerosol formation, growth, and transport — bridging molecular and nanoscale particle properties with their regional and global impacts on weather, air quality, renewable energy, and climate.

Using the ICON-ART modeling framework, we analyze traffic emissions, dust outbreaks, vegetation fires, and volcanic eruptions as natural experiments to unravel aerosol–atmosphere interactions under real-world conditions. Our group initiated and leads the development of the ART submodule within the ICON model system. ART enables the consistent simulation of emissions, transport, chemical transformation, and aerosol–cloud–radiation interactions of aerosols and trace gases across scales.
