Short summary
In summer 2023, Greece experienced one of its most intense wildfire seasons, with major fires across several regions. This study examines how smoke from two major fire events affected air quality and ultraviolet radiation in Athens using satellite images, modelling, and ground-based measurements to understand the optical and microphysical behavior of airborne particles.
