ESA is planning a new instrument to improve the retrieval of meteorological parameters from geostationary orbit. The new sounder will follow the path set by JPL's Geostar project. 

The idea is to improve weather and severe storm forecasting by taking all-weather and full hemispheric soundings (at about 25 km resolution every ~15 minutes, and continuously). 

 

The project is done in collaboration with China, Prof. Tapiador has been appointed by ESA as one of the three members of the Advisory Committee of the Geosounder project.
