APSDEU-7/ September 2006/ NOAA 13 Polar Orbiting Satellites Current Status KMA has three different sites for receiving data from polar-orbiting satellites. Seoul (KMA) : NOAA-12, 17, 18 Seosan (100 km southwest from Seoul) : NOAA-15, FY-1D Munsan (50 km northwest from Seoul) : Terra, Aqua On-going Since July 2004, the raw pass data of FY-1D are directly received. IR (Ch 4) images of FY-1D have been produced for forecast since October We are testing the L1B data to produce derived products from FY-1D. Future Plan KMA has the plan to receive data from the polar orbiting satellites of next generation. METOP (2007), NPP (2009), NPOESS (2012?-)

APSDEU-7/ September 2006/ NOAA 35 Background and history It was discussed at APSDEU-6 that ATOVS data would be exchange in Asia-Pacific area. It was decided that Tokyo and Beijing would be the intra-regional data centers. First exchange test within A-P area would have been finished till the end of KMA has started the detailed discussion to implant RARS system with JMA since May Format and telecommunication method for ATOVS data exchange was finalized according to the discussion with JMA. KMA prepared the encoding and decoding program for ATOVS data during June KMA debugged errors in BUFR data to be ready for data exchange from July to early August KMA finished to produce ATOVS BUFR data to be exchanged with JMA by August 2006

APSDEU-7/ September 2006/ NOAA 36 Current Status and Future Plan Data to be exchanged : ATOVS AAPP L1C (HIRS, AMSU-A, AMSU-B) Data format : Compressed BUFR Telecommunication : GTS between Seoul and Tokyo Data from Seoul to Tokyo : 1 HRPT station (Seoul) Data from Tokyo to Seoul : 9 HRPT station (2 Japan, 3 China, 4 Australia) First test exchange succeeded on 15 September between Seoul and Tokyo. Data exchange for routine operation would be performed since 20 September. Exchanged ATOVS data will be utilized in regional NWP model
