Polar Orbiting SatellitesPolar Orbiting SatellitesCurrent Status
KMA has three different sites for receiving data from polar-orbiting satellites.Seoul (KMA) : NOAA-12, 17, 18Seosan (100 km southwest from Seoul) : NOAA-15, FY-1DMunsan (50 km northwest from Seoul) : Terra, Aqua
On-goingSince 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 2004.We are testing the L1B data to produce derived products from FY-1D.
Future PlanKMA has the plan to receive data from the polar orbiting satellites of next generation.METOP (2007), NPP (2009), NPOESS (2012?-)

APSDEU-7/ 20-22 September 2006/ NOAA35
Background and historyBackground and historyIt 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 2005.KMA has started the detailed discussion to implant RARS system with JMA since May 2006.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 2006.KMA debugged errors in BUFR data to be ready for data exchange from July to early August 2006.KMA finished to produce ATOVS BUFR data to be exchanged with JMA by August 2006
