  2. COSMO-LEPS Products of MeteoSwiss

  3. Current activities & future plans • 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.
