About

Claus Zehner is a leading figure in satellite-based atmospheric remote sensing, with a primary focus on advancing aerosol monitoring for air quality and climate research. His most cited work, "SEVIRI Aerosol Optical Depth Validation Using AERONET and Intercomparison with MODIS in Central and Eastern Europe" (2021, 8 citations), exemplifies his commitment to rigorous validation of satellite retrievals. In this study, Zehner and his team validated Aerosol Optical Depth (AOD) from the Spinning Enhanced Visible Infrared Radiometer (SEVIRI) against ground-based AERONET measurements, demonstrating the algorithm's reliability for near-real-time air quality applications. This work was conducted within the Satellite-based Monitoring Initiative for Regional Air quality (SAMIRA) project, a key platform for his contributions. Zehner’s research bridges the gap between satellite observations and operational air quality monitoring, providing critical tools for policymakers and environmental agencies. His impact is reflected in the growing use of his validated datasets for regional and global aerosol studies. By combining technical rigor with practical applications, Zehner has established himself as a vital contributor to Earth observation science, helping to transform satellite data into actionable environmental intelligence.
