HaiYang-1C/D (HY-1C/D) constitute China’s optical satellite constellation for global ocean monitoring (one in the morning and the other in the afternoon) and could increase the frequency of observations. The new sensors like Ultraviolet Image (UVI) and Satellite Calibration Spectrum (SCS) onboard HY-1C satellite will improve the atmospheric correction accuracy and the ocean color quantitative observation level of the nearshore turbid water body. The Coastal Zone Imager (CZI) can provide optical images with a wide swath of 950 km and moderate spatial resolution (50 m), for the coastal environment and resources monitoring from space. The Automatic Identification System (AIS) could obtain ship location and attributes information. HY-1C satellite data could meet the demand of ocean color, temperature, coastal zone and ocean disaster and ocean environmental monitoring. It also serves natural resource survey, environmental ecology, emergency disaster reduction, meteorology, agriculture and water conservancy, etc.
