There is presently no sufficiently developed European or Canadian expertise for the exploitation of Doppler measurements from space radars.

This activity would be two fold:
1. Exploitation of the potential of a new technology for meteorological applications and,
2. assessment of the potential of a new mission concept, based on a single instrument.

The results of the study will lay the foundation for the interpretation and exploitation of radar Doppler measurements for cloud modelling (in climate and weather models) and atmospheric data assimilation.

It will furthermore be essential the establishment of observational requirements for space-borne Doppler radars and allow the quantitative assessment of their performance. Finally, it will be instrumental for strengthening European expertise in the scientific and operational exploitation of Doppler observations from space-borne radars, including the Japanese CPR onboard EarthCARE and potential future Doppler radar missions.
