Neural network sharpens satellite ocean color in complex coastal waters
Tokyo, Japan (SPX) Jan 01, 2026 A recent study presents ACA-SIM, an atmospheric correction algorithm that uses satellite-in situ matchup data and neural networks to improve ocean color retrievals over coastal waters. The approach relies on real satellite radiance and in situ reflectance from Aerosol Robotic Network-Ocean Color (AERONET-OC) sites to reduce errors and striping artifacts in derived ocean color products, particularly in turbid and complex aerosol conditions such as the Bohai Sea, North Africa dust regions, and Australian ... read more |
