新一代海洋水色观测卫星海岸带成像仪渤海湾局部遥感影像

封面图片展示的是中国新一代海洋水色观测卫星海岸带成像仪于2025年1月19日获取的天津港及邻近水域20 m分辨率遥感影像，该影像清晰呈现了入海河流、港口设施及周边水体的水色特征分布。海岸带成像仪具备20 m分辨率多光谱和5 m分辨率全色波段的协同观测能力，其获取的数据可有效应用于海岸线变迁监测、海岸工程建设评估、河口生态系统研究以及近岸水体环境参数反演等研究领域。2023年11月16日成功发射的该卫星还搭载了第二代水色水温扫描仪和中分辨率可编程成像光谱仪，通过多分辨率、多光谱的协同观测方式，为海洋灾害、海洋生态系统、海洋资源、全球大洋与极地环境监测提供了重要的数据支撑。

Remote sensing image covering a local region of the Bohai Bay by the China’s new-generation ocean color observation satellite

The cover image presents a 20-meter resolution remote sensing image of Tianjin Port and its adjacent waters, acquired by the second-generation Coastal Zone Imager (CZI2) aboard China's new-generation ocean color observation satellite on January 19, 2025. This image distinctly reveals the characteristic color signatures of inflowing rivers, port infrastructure, and surrounding waters. The CZI2 possesses synergistic observation capabilities with its 20-meter resolution multispectral bands and 5-meter resolution panchromatic band. Data acquired by the sensor can be effectively applied in research domains including monitoring of coastline changes, assessment of coastal engineering projects, studies of estuarine ecosystems, and retrieval of environmental parameters in nearshore waters. Successfully launched on November 16, 2023, the satellite is also equipped with a second-generation ocean color and sea surface temperature scanner (COCTS2) and a Programmable Medium-Resolution Imaging Spectrometer (PMRIS). Through their multi-resolution, multispectral synergistic observation approach, these sensors provide crucial data support for monitoring of marine disasters, marine ecosystems, marine resources, and global oceans and polar environments.
