Data Service Sub. System Domestic and overseas Regular institution 11

Data Service Sub. System Irregular institution and Huge capacity user 12

Data Service Sub. System Method and Data by service Division Regular institution Data service Type of data provided Satellite - GK 2 A - COMS - Space weather Data level & Format - L 1 b(Bin, Img) - Space weather Due day Service object Provide etc - Real time - Lately 72 hours - Regular agency User - FTP (Get, Put) - DMZ storage Irregular institution - GK 2 A - L 1 b(Bin, Img) Data - COMS - L 2(Bin, Img) - Whole period - Irregular agency User - Web - request - storage service Large capacity Data service - GK 2 A - COMS - Foreign Satellite - L 1 b(Bin, Img) - L 2(Bin, Img) - Whole period - Domestic research institute - Web - request - storage 13

Summary GK-2 A Broadcast all 16 channels data (UHRIT, full resolution) of meteorological observations Real-time cloud service similar to Himawari Cloud will be implemented (< 5 min data latency) Himawari-8 in NMSC – Received all 16 channels data(Cloud) of whole area – Received all 14 channels data(cast) of full disk – create into binary and image files according to predefined each areas Data processing subsystem – Processing begins before the next data comes in – message delivery method and consists of an operation management engine and a work flow engine – generating 52 kinds of meteorological product and utilization Data service subsystem – Use satellite broadcasting, landline – Plan to provide image generation tool Future work – Greater accuracy of weather forecasts based on operation of subsequent ground segments for meteorological satellites 14
