About

Denghui Ji is a climate scientist specializing in Arctic amplification and atmospheric remote sensing, with a focus on understanding the mechanisms driving the Arctic’s accelerated warming relative to the global average. His key research areas include ground-based remote sensing of aerosol properties, high-resolution infrared emission spectroscopy, and lidar observations in the High Arctic. Ji’s major contribution lies in integrating multi-instrument observational techniques to characterize aerosol–cloud–radiation interactions, which are critical yet poorly constrained feedbacks in Arctic climate models. His most-cited work, “Ground-based remote sensing of aerosol properties using high-resolution infrared emission and lidar observations in the High Arctic” (2023, 5 citations), exemplifies his approach by combining spectral infrared and lidar data to retrieve aerosol optical properties under extreme polar conditions. This research directly supports the Transregional Collaborative Research Centre “TRR 172: ArctiC Amplification” (AC)³, a major German initiative aimed at unraveling surface–atmosphere feedback processes. Ji’s findings help refine satellite retrievals and improve climate predictions, making his work essential for researchers studying polar amplification and its global implications.
