“海洋- 1c”是中国首颗可运行的海洋颜色卫星，旨在获取全球海洋颜色的日常数据。船上的紫外线成像仪（UVI）为海洋石油泄漏的检测提供了一种潜在的新型探测器。虽然机载紫外线传感器在泄漏油的检测方面表现出了很高的效率，但星载紫外线传感器的能力尚不清楚。在本研究中，我们设计了一个地面实验来解释各种风化油的紫外线特性，发现非常薄的油膜由于表面干涉光对紫外线辐射非常敏感。此外，通过对HY-1C UVI和AVIRIS采集的泄漏油的星载和机载紫外线图像进行比较，清楚地解释了紫外线遥感的尺度效应。干涉光和太阳光反射在溢油成像过程中发挥着不同的作用，导致它们在地面、机载和星载观测中呈现出截然不同的特征（比背景无油海水更亮或更暗），值得进一步研究。因此，紫外线遥感可以作为一种新的方法，改善海洋溢油的检测和监测。
Haiyang-1C (HY-1C) is the first operational ocean color satellite of China, which is intended to obtain daily global ocean color data. The Ultraviolet Imager (UVI) onboard provides a potential novel detector for the detection of marine oil spills. Although airborne UV sensors have shown great efficiency for the detection of spilled oils, the capability of spaceborne UV sensor is not yet clear. In this study, we designed a ground-based experiment to interpret the UV characteristics of various weathered oils, and found that very thin oil films are quite sensitive to the UV radiation due to the surface interference light. Moreover, by comparing spaceborne and airborne UV images of spilled oils collected from HY-1C UVI and AVIRIS, the scale effect of ultraviolet remote sensing has been interpreted clearly. The interference light and sunglint reflection play different roles in the imaging process of spilled oils, leading them to appear radical different features (brighter or darker than the background oil-free seawater) in ground, airborne and spaceborne observation, which deserves further research. Ultraviolet remote sensing, therefore, can work as a new approach and improve the detection and monitoring of marine oil spills.
