  • The pre-launch system preparation and post launch evaluation of new satellite observations prior to operational use - including impact assessment with assimilation experiments in the ECMWF analysis and forecasting system
  • Developing advanced science and technology to extend and improve the exploitation and impact of radiance observations for NWP.
  • Some international travel may be required to represent ECMWF at external meetings and scientific conferences

5. Personal attributes
