Abstract

Water quality inversion model based on satellite images could provide a good complement for coastal hydro-environment monitoring in the Hong Kong waters. However, previous studies attempted to establish a single inversion model for expressing the whole Hong Kong waters without considering the regional differences of water properties. In this study, the whole Hong Kong waters is firstly divided into 6 clusters for the inspection of their respective water quality characteristics. The local models for a specific cluster are then developed and compared with the original single model results for the Hong Kong water quality analysis. It shows that the results obtained by the cluster-based local inversion models are comparable to or even better than those by the original single models, thereby providing a more effective tool for the coastal water quality management in Hong Kong.
