From October 24th to 31st, the International Ocean Color Coordination Working Group (IOCCG), the European Copernicus Program and the European Organization for the Exploitation of Meteorological Satellites (EUMETSAT), and the National Key Laboratory of Satellite Marine Environmental Dynamics of the Second Institute of Oceanography (SOED/SIO /MNR), the National Satellite Ocean Application Center (NSOAS) and the Institute of Geographic Information Science of Zhejiang University (GIS/ZJU) jointly organized the "2019 Advanced Training Course on Ocean Color Remote Sensing" (IOCCG training for short) class successfully completed in Hangzhou. This training course lasted for one week, and 20 students were selected from more than 60 applications from various Asian countries, including 8 students from Bangladesh, Egypt, South Korea, Thailand, India, Indonesia and other countries, and 12 students from Zhejiang University and Xiamen University, Nanjing University, Ocean University of China, Hohai University, Southern University of Science and Technology, Wuhan University, Shenzhen University, Xi'an Institute of Optics and Precision Mechanics of the Chinese Academy of Sciences, the Second Institute of Oceanography and other domestic universities and scientific research institutions.

During the training, Lauren Biermanm and Dr. Oliver Clements from Plymouth Marine Laboratory in the UK introduced the downloading, analysis, visualization and quality assessment of the European Organization for the Exploitation of Meteorological Satellites' Copernicus data series respectively. Researcher He Xianqiang from the Second Institute of Oceanography taught the principles of ocean color satellites and atmospheric correction technology. Deputy researcher Tao Bang explained the remote sensing monitoring methods of harmful algal blooms and offshore water quality. Researcher Bai Yan introduced the theoretical framework of ocean carbon cycle remote sensing and satellite remote sensing algorithms of key carbon parameters. Assistant researcher Chen Xiaoyan explained the analysis of long-term series satellite ocean data and its application in ocean climate oscillations.

In addition to systematic lectures on special topics, each topic also includes corresponding hands-on exercises. Students are divided into four groups to jointly carry out small remote sensing application projects. In addition, training on lake measurements with optical instruments was conducted. In the final report on the last day, student representatives used the knowledge and skills learned in the course to demonstrate the results of small projects such as using remote sensing data to conduct atmospheric correction and comparison of multi-source remote sensing data, environmental detection of fisheries, the impact of typhoon events, and monitoring of hypoxic zones in the East China Sea.

In just one week, members of each group fully discussed and communicated, shared experiences and knowledge, not only demonstrated their success and application of what they learned, but also gained friendship. Each trainee expressed their thoughts, suggestions and thanks for the training class. Finally, researcher He Xianqiang, executive member of IOCCG, and Lei Jijiang, deputy director of the Personnel Department of the Second Institute of Oceanography, issued graduation certificates to all the trainees.

This training course mainly provides data support for the European Organization for the Application of Meteorological Satellites' Copernicus data series and China's ocean color satellite data, as well as training on ocean color remote sensing technology and applications for Asian countries. Mutually beneficial and win-win scientific and technological exchanges in the application field have also played a great role in promoting the promotion and application of the SOED National Key Laboratory's achievements and technologies.
