    Aeolus

    The Aeolus mission which was launched into space on 22 August 2018 and was retired on 30 April 2023, provided global observations of wind profiles from space to improve the quality of weather forecasts, and to advance our understanding of atmospheric dynamics and climate processes.

    CryoSat

    CryoSat determines variations in the thickness of continental ice sheets and marine ice cover. Europe's first ice mission is an advanced radar altimeter specifically designed to monitor the most dynamic sections of Earth's cryosphere.
