"The satellite was launched on a Long March 4B Y53 carrier rocket and has successfully entered its preset orbit,” the China National Space Administration(CNSA) said, according to Xinhua news agency.

The satellite will fill the gap of China’s high-precision global ocean-salinity detection capabilities, improve data collection on ocean dynamics and environmental factors, and boost the accuracy of China’s marine forecasting products, said the CNSA.

It will also support marine environmental forecasting, ecological forecasting, water-cycle monitoring, short-term climate prediction, and global climate change research, providing critical data for applications in agriculture, disaster mitigation, meteorology and other related industries, CNSA added.

It is noteworthy ,that this flight mission was the 545th for the Long March series rockets.
