  3. Operations & maintenance all 6 members - individual operational applications almost the same domains mesh size (x 12.2km - x 6.5 km) vertical resolutions (L37 - L45) 00 and 12 UTC runs per day 06 and 18 UTC runs on demand envelope - no envelope orography dyn. adapt; blending; 3DVar (e-suite) maintenance and porting of SW RC LACE 27th EWGLAM Meeting 3-5 October 2005, Ljubljana

  4. Networking in 2004/2005 (Who? Why?
