His research offers an approach to integrating Earth Observation data with in situ measurements for a more nuanced understanding of urban air pollution, focusing on NO2 and PM10 levels in Würzburg. Andreas’s work demonstrates the potential of combining satellite data from the Copernicus Sentinel-5P, regulatory readings, and low-cost sensor networks for detailed air quality analysis. Conducted under the guidance of Prof. Dr. Hannes Taubenböck and Prof. Dr. Tobias Ullmann, the thesis is a contribution to applied Earth Observation and Geo-analysis, emphasizing the importance of interdisciplinary methods in environmental science.
