About
Christian A. Gueymard is a leading authority in solar resource assessment and clear-sky radiation modeling, with a career dedicated to improving the accuracy of solar energy predictions. His research focuses on the critical role of atmospheric constituents—particularly aerosols and precipitable water—in determining the quality and quantity of solar irradiance reaching the Earth's surface. Gueymard’s major contributions include the rigorous validation of satellite-derived aerosol optical depth (AOD) and precipitable water data against global ground-based networks like AERONET. His landmark 2019 study, which validated MODIS AOD across 452 stations, has garnered 82 citations, underscoring its foundational impact on the field. He has also advanced direct normal irradiance modeling by evaluating the influence of gridded aerosol databases and pioneered the reconstruction of historical AOD time series using proxy meteorological data. More recently, Gueymard has validated satellite-based spectral irradiance products for photovoltaic applications and assessed aerosol forecast performance in challenging regions like the Middle East. His work is essential for reducing uncertainty in solar energy resource assessment, directly benefiting the design and bankability of solar power plants worldwide.
