KSWC format
Japan STELAB format
Make a standard format from each IPS telescope and use as model input
• Model run test with hybrid data (Nagoya + KSWC)
STELAB data STELAB + KSWC data
Compare the result of ENLIL & IPS
• Synchronize the model output results and compare two models• 7 days (-2/+5) prediction results, 6 hours cadence

: ENLEL only case, : IPS only case
• Color lines represent that only one model predicts the CME• This results shows that each models have their own advantage
Summary• KSWC have been operating two solar wind prediction models from 2013
ENLIL with CONE IPS
Start of model run at KSWC
Jan, 2013 May, 2013
Developer Dr. Dusan Odstricil Dr. Bernard V. Jackson
Computing infra 2 x IBM X3550 (4 GB ram) 2 x IBM X3250 M4 (4 GB ram)
Running time ~ 2.5 hours (every 4 hours) ~ 0.5 hours ( everyday)

Summary
• Korean IPS system– For operational purpose
– Owned by KSWC which is government agency
–Maintained by SETsystem, Inc. which is system developer and contractor for operation
• To do– Data quality check, single site obs. use model
fitting technique
– Combine of the ENLIL and IPS model
