Abstract

An at-sensor radiance simualtion environment based on the atmosphere-ocean coupled model OSOAA for case-I and case-II waters is set up for evaluation of arbitrary combinations of sensors. Simulated results show that the 385 nm and 355 nm channels are sensitive to chlorophyll when it is less than 2.5 mg/m³ , sensitive to suspended sediment when it is less than 2.5 mg/L, and sensitive to CDOM when a_CDOM is less than 0.08 m−1. The quantification of dynamic range for TOA (top of atmosphere) radiances should help to design the forthcoming ultraviolet ocean-color satellite sensors, e.g. the UVI (UltraViolet Imager) on HY-1/C (HaiYang-1/C) of China, as well as correctly exploit the satellite data aquired by the future ultraviolet satellite sensors.
