Recent Developments EURO_HRM Model  Introduction of asynoptic observations into operational data assimilation suite (AMVs from Meteosat 5-7-8, Quikscat winds, AMDAR-ACAR, Wind profilers)  Increase of horizontal resolution (0.5 -> 0.25 deg)  Small increase of integration domainintegration domain  Introduction of non separable BG error correlation functions in the 3DPSAS objective analysis  New post processed products EWGLAM - SRNWP, Oslo 4-7 October 2004

Recent Developments EURO_LM Model  Large increase of integration domainintegration domain  Initial Conditions from Euro_HRM 3DPSAS analysis EWGLAM - SRNWP, Oslo 4-7 October 2004

Current Developments  Increase of vertical levels (Euro-HRM: 31 -> 40)  Experimental assimilation of ERS2 scatterometer winds and interactive ATOVS 1DVAR retrievals  Introduction of FGAT in the data assimilation cycle  Development of MOS statistical package for surface weather parameters from Euro_LM model output  Acquisition of local computing capacity: Linux cluster with app. 70 Opteron nodes with Myrinet interconnect EWGLAM - SRNWP, Oslo 4-7 October 2004
