2 COSMO-LEPS Products of MeteoSwiss

3 COSMO-LEPS suite as time-critical application at ECMWF MARS archiving of COSMO-LEPS products 3-hourly boundary conditions Participation to EURORISK-PREVIEW project: integration domain will be enlarged to include Northern Europe; clustering on different areas will be tested. Participation to MAP D-PHASE project: further downscaling (around 2 km hor. res.) on specific areas where severe events are likely to occur Coupling with hydrologic models Focus on verification. Current activities & future plans
