About

Ouahid Aznay is a remote sensing scientist whose research has advanced the atmospheric correction of satellite imagery, particularly for ocean-color and land applications. His core contributions focus on improving aerosol retrieval algorithms for the Medium Resolution Imaging Spectrometer (MERIS) onboard ENVISAT. Aznay’s most cited work, “Evaluation of the MERIS aerosol product over land with AERONET” (32 citations), rigorously validated satellite-derived aerosol optical properties against ground-based AERONET measurements, establishing a benchmark for product accuracy. He further developed a new climatology for atmospheric correction based on aerosol inherent optical properties (16 citations), enhancing the physical basis of aerosol models used in processing. His validation of MERIS aerosol models over coastal waters (10 citations) addressed critical challenges in ocean-color remote sensing, ensuring more reliable retrievals in optically complex environments. Aznay also contributed to lunar calibration techniques for the Pleiades satellite constellation, supporting long-term sensor stability. With a career spanning aerosol phase function derivation from CIMEL measurements and validation of atmospheric scattering functions, his work remains foundational for researchers working on satellite-based aerosol and ocean-color monitoring, directly supporting climate and environmental studies.
