About

Alexander Haefele is a leading figure in atmospheric remote sensing, with a focus on aerosol profiling and the integration of lidar and sun-photometer technologies. His major contributions center on advancing combined inversion methods to retrieve aerosol optical properties with unprecedented accuracy, as demonstrated in his highly cited work from the EARLINET/ACTRIS COVID-19 campaign. This study, which has garnered 5 citations, leveraged a continent-wide observational effort during the May 2020 lockdown to monitor atmospheric changes, showcasing his ability to coordinate large-scale, real-world experiments. Haefele’s research has significantly improved our understanding of aerosol vertical distribution and its impact on climate and air quality, providing critical data for model validation. His achievements include key roles within the European Aerosol Research Lidar Network (EARLINET) and the ACTRIS infrastructure, where he has driven collaborative innovation. For students and researchers, Haefele’s work exemplifies how precise instrumentation and international teamwork can unravel complex atmospheric processes, making him a vital contributor to the field of environmental monitoring.
