The 650-kilogram (1,430 pound) machine is the first satellite jointly built by China and France and will allow climate scientists to better understand interactions between oceans and the atmosphere.

The satellite is fitted with two radars: the French-made SWIM, which will measure the direction and the wavelength of waves, and China's SCAT, which will analyse the force and direction of winds.
