Johannes Quaas

Johannes Quaas is a Professor of Theoretical Meteorology and Vice Dean of the Faculty of Physics and Earth System Sciences at Leipzig University. His research focuses on cloud processes and their role in climate change, with particular emphasis on anthropogenic aerosols' effects on clouds and climate. He is a lead contributor to the IPCC Assessment Reports and leads multiple European collaborative research projects while maintaining active roles in the German Meteorological Society and University Partnership for Atmospheric Sciences.

Professor Quaas's research spans cloud-climate interactions, parameterization of cloud processes in climate models, satellite observations of atmospheric phenomena, aerosol-cloud-precipitation-radiation interactions, and the relationship between biodiversity and climate change. His methodology combines climate modeling with satellite data analysis to understand how human activities influence atmospheric processes. Recent work increasingly incorporates machine learning techniques to improve cloud parameterizations in climate models and analyze complex satellite datasets, demonstrating his ability to integrate emerging computational methods with fundamental atmospheric science.

Analysis of Professor Quaas's publication record reveals a consistent focus on aerosol-cloud interactions, with growing emphasis on machine learning applications and biodiversity-climate connections. His work bridges observational studies, climate model development, and fundamental physical investigations of cloud processes. The research has significant implications for understanding climate sensitivity, improving climate model projections, and assessing potential climate intervention strategies. His leadership in multiple major research projects demonstrates his standing as a key contributor to advancing our understanding of climate system dynamics.

Professor Quaas leads several major research initiatives including ECO-N (The Economics of Connected Natural Commons - Atmosphere and Biodiversity), WarmWorld (calibrating liquid water cloud microphysics in ICON), CleanCloud, and VolCloud (studying volcanic influences on clouds). His work receives funding from prestigious organizations including the German Research Foundation (DFG), Federal Ministry of Education and Research (BMBF), and European Union, reflecting the significance and impact of his research program.

As Vice Dean of the Faculty of Physics and Earth System Sciences, Professor Quaas provides academic leadership while maintaining an active teaching schedule. His courses span theoretical meteorology topics including Differential Equations, Dynamics, Global Climate Dynamics, Thermodynamics, and Climate Crisis and Solutions. This teaching portfolio reflects his commitment to training the next generation of atmospheric scientists while addressing contemporary climate challenges through education.
