Phase 0 UCM Presentation for the Earth Explorer 12 Candidate Mission Hydroterra+

This presentation forms the basis for recommending up to two mission candidates to proceed to Phase A, for the twelfth Earth Explorer mission, within the European Space Agency’s Future Earth Observation (FutureEO) Programme. It presents the Hydroterra+ mission concept, which has successfully completed its Phase 0 preparation. Hydroterra+ would be placed in geostationary orbit, which is innovative for an Earth-science radar mission. From this fixed position above the equator, the satellite’s C-band synthetic aperture radar would deliver data products multiple times a day over Europe, the Mediterranean and northern Africa to understand rapid processes tied to the water cycle over land and to extreme events in these regions.
