Outlines

  • Context and Introduction.
  • Basic theory of the two measurements: radial wind and reflectivity
  • Sources of measurement errors: need for pre-processing radar data.
  • The specific radar product for AROME
  • Towards the assimilation of radial winds: observation operator, quality control and thinning
  • Towards the assimilation of reflectivities: observation operator, specific methodology for reflectivities, quality control, and thinning
  • Assimilation status for reflectivities: results through case studies.
  • Assimilation status for radial winds : results and impact on short forecasts through case studies.
  • Conclusions and perspectives
