About

Dr. Masahiro Hori is a leading figure in satellite ocean color remote sensing, specializing in the vicarious calibration and validation (Cal/Val) of next-generation spaceborne imagers. His research centers on ensuring the radiometric accuracy of sensors like the Global Imager (GLI) and the Second generation Global Imager (SGLI) aboard the GCOM-C mission, which is critical for reliable climate data records. Dr. Hori’s major contributions include pioneering vicarious calibration techniques using ground-based measurements—such as the Marine Optical Buoy (MOBY) and AERONET-OC data—to correct satellite-derived water-leaving radiance and aerosol optical properties. His 2005 work on GLI calibration, cited 21 times, established foundational methods for sensor stability monitoring. More recently, his 2022 study (14 citations) validated SGLI products in the optically complex Ariake Sea, Japan, demonstrating the practical application of AERONET-OC stations for coastal water quality assessment. By bridging in situ observations with satellite data, Dr. Hori has enhanced the accuracy of global ocean color products, directly supporting climate change research and aquatic ecosystem monitoring. His work remains indispensable for scientists relying on satellite-derived ocean data.
