Georgia Alexandri

About

Georgia Alexandri is an atmospheric scientist whose research focuses on aerosol remote sensing, satellite-based observations, and air quality monitoring across major global regions. Her work centers on characterizing aerosol optical depth (AOD) — a key measure of atmospheric particulate matter — using data from multiple satellite platforms including MODIS, ATSR-2, and AATSR. Alexandri has made significant contributions to understanding long-term aerosol variability, particularly over mainland China and the Eastern Mediterranean. Her landmark 2018 study evaluating two decades of satellite AOD observations over China, which has accumulated 146 citations, demonstrated the value of combining multiple satellite datasets to reveal large-scale pollution patterns and trends. Complementing this, her spatiotemporal analysis of aerosol types over the Eastern Mediterranean (102 citations) illuminated how dust, smoke, and anthropogenic pollutants differentially contribute to regional air quality dynamics. A hallmark of her methodology is the integration of multi-satellite datasets spanning extended time periods, enabling robust trend analyses that single-instrument studies cannot achieve. Her multi-part series on aerosol variations over China further solidified her reputation as a leading voice in satellite aerosol climatology. With over 330 combined citations across her most influential works, Alexandri's research provides foundational datasets and insights for climate modeling, public health assessments, and environmental policy development.
