An Introduction to Optical Remote Sensing of the Asian Seas: Chinese Dedicated Satellites and Data Processing Techniques
The application of optical remote sensing in the Asian Seas is introduced, by reviewing the achievements of ocean colour dedicated missions and data processing techniques in China. Two satellites (HY-1A and HY-1B) have already been launched as part of the Chinese long-term (2015–2025) ocean colour observation program, which foresees the launch of more than 15 orbital platforms. Data processing techniques, including the development of a vector radiative transfer model, as well as calibration, polarization correction, and atmospheric correction algorithms, have all been developed specifically for these missions, with particular attention to the peculiar environmental conditions of the greater China Sea. Progress on the atmospheric correction effectiveness in highly turbid waters in the greater China Sea coastal regions is also examined.
