Presentation of Eric Wattrelot during the 2nd AROME training course, Lisbon, 4-7 March 2008 : "Assimilation of radar data in the
AROME model AROME model at at Météo Météo-France France" by Eric Wattrelot, Olivier Caumont, Thibaut Montmerle, Claudia Faccani, Marian Jurasek and Günther Haase.

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
