6. Update of TIGGE data provider : LFPW(Meteo France) : since 8 Dec. 2009 ， increasing 29274 fields at 06Z and 35152 fields at 18UTC RKSL(KMA) : since 18 Dec 2009, increasing 3009 fields at 00Z and 12UTC ECMWF: increasing model resolution from N200 to N320 ， data up to 330GB/day

7. CMA portal offers services: - Access to online & offline data - Aggregation along any axis (date, level, parameter, origin, ensemble, …) - Product Generation on Webpage - Request Monitoring and Query - User Management and Access Control - Sub-area selection - Reduces volumes to be downloaded by many order of magnitude ( Divided into more small tar files )
