After many years’ endeavor of research and application practice,the ocean color remote sensing in China has been growing into a new technique with valuable practicality from its initiate stage of trial research.With the aim of operational service,several kinds of ocean color remote sensing application systems have been developed and realized the long-term marine environmental monitoring utilizing the real-time or near real-time satellite and airborne remote sensing data.New progresses in the technology and application of ocean color remote sensing in China are described,including the research of key techniques and the development of various application systems.Meanwhile,according to the application status and demand,the prospective development of Chinese ocean color remote sensing is brought forward.With Chinese second ocean color satellite(HY-1B)orbiting on 11 April 2007 and the development of airborne ocean color remote sensing system for Chinese surveillance planes,great strides will take place in Chinese ocean color remote sensing application with the unique function in marine monitoring,resources management and national security,etc. After many years’ endeavor of research and application practice, the ocean color remote sensing in China has been growing into a new technique with valuable practicality from the start stage of trial research.With the aim of operational service, several kinds of ocean color remote sensing application systems have been developed and realized the long-term marine environmental monitoring utilizing the real-time or near real-time satellite and airborne remote sensing data.
