About
Ioannis-Panagiotis Raptis is a leading atmospheric physicist whose research centers on aerosol climatology, aerosol optical properties, and the direct radiative effects of aerosols on surface solar radiation. His most impactful contribution is a landmark decade-long study (2008–2018) of aerosol optical properties over Athens, Greece, using ground-based measurements from the National Observatory of Athens—a work that has garnered 73 citations and established a foundational aerosol climatology for the region. Raptis has also advanced methodological accuracy by evaluating how columnar nitrogen dioxide (NO₂) biases retrievals of aerosol optical depth (AOD), Ångström exponent, and single scattering albedo from sun–sky radiometers. In applied work, he quantifies the direct effect of aerosols on Global Horizontal Irradiance (GHI) and Direct Normal Irradiance (DNI), with a focus on the Mediterranean Basin, demonstrating critical implications for solar energy forecasting and resource assessment. His research bridges fundamental atmospheric science and renewable energy applications, making him a key figure in understanding aerosol–radiation interactions and their societal impacts.
