Abstract Bohai Sea, with the highest suspended sediment concentration in world, has experienced a sharp decrease sea surface (SSSC) latest two decades. However, limited by shortage of long‐term field observations, spatiotemporal characteristics and mechanisms variation SSSC are still unclear. Based on remote sensing data, this study reconstructed distribution from 2003 to 2016, found significant spatial difference decadal Sea. The largest was observed southern Sea an average annual 1.3 mg/L...
Abstract System Vicarious Calibration (SVC) enhances the accuracy of satellite ocean color radiometric data products by removing bias due to intrinsic inaccuracies affecting both responsivity space sensor and correction for atmospheric sea surface contributions measured signal. Various SVC procedures have been implemented applied regional studies, specific mission goals, most challenging quantification global, long-term, climate-driven changes that require accurate consistent across multiple...
Variable marine environmental conditions, particularly at the sea surface, present considerable challenges to cross-media laser transmission. This study simulates uplink transmission through a seawater-sea surface-air channel via ray tracing and Monte Carlo methods, with an emphasis on impacts of surface channel.
