Monday 31 March 2008 par Patricia

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.
