ADM-Aeolus: ESA's wind mission
The Earth Explorer Atmospheric Dynamics Mission (ADM-Aeolus) is named after Aeolus, who in Greek mythology was appointed "keeper of the winds" by the Gods. It will be the first-ever satellite to observe wind profiles from space on a global scale. The Aeolus satellite will carry a powerful Doppler wind lidar (in the ultraviolet spectral region at 355 nm) that has never been flown in space before. This technology will make it possible to probe the lowermost 30 km of the atmosphere to measure the winds sweeping around our planet. Wind observations acquired during EUREC4A will help evaluate and calibrate the wind retrievals from this space mission. In turn, ADM-Aeolus observations will help put the EUREC4A observations into a larger context.
EarthCARE: ESA's cloud, aerosol and radiation mission
This Earth Explorer mission, developed jointly between ESA and the Japan Aerospace Exploration agency JAXA, aims at advancing our understanding of the role of clouds and aerosols in climate. It will employ a high-performance lidar and radar technology (doppler cloud radar and lidar) that has never been flown in space before to acquire vertical profiles of clouds and aerosols, as well as radiances at the top of the atmosphere. Observations of clouds and radiation collected during the EUREC4A field study will help evaluate and improve the EarthCARE retrievals. In turn, EarthCARE observations will help put the EUREC4A observations into a larger context.
