1. Current verification results for COSMO-EU and COSMO-DE at DWD
Ulrich Damrath & Ulrich Pflüger

2. Outlook What happened during last year concerning model development?
: Gust diagnosis (changing basic wind level for diagnostics from 30 to 10m)
: Calculation of 2m temperature (changing z0 to 2 cm)
: Changes in the convection scheme to avoid unrealistic high precipitation values
Do we see these changes when looking at the verification results?
Comparison of results for different seasons
Comparison of COSMO-DE and COSMO-EU using traditional verification methods
Diurnal cycles for different elements
