1 Site Report Korean IPS system at KSWC Jung-Hoon Kim & Jincheol No (SETsystem, Inc.)

2 IPS SYSTEM

3 Korean IPS array is deployed at KSWC in Jeju Island, Korea

4 Korean IPS Array Antenna Crossed Dipole with LNA Center Freq: 327MHz Tile 24 dipole on 1 tile Beam former Node 4 tiles = 1 node Node box A/D conversion and GPS clock sync. Whole system Total 768 antennas on 32 tiles with control and data processing system Node (4 tiles makes 1 node) Crossed-dipole Antenna Tile (24 dipoles with reflecting mesh) Whole system 4

5 System Specification 32 tiles deployed over 250 x 250 m 2 (1tile=24 dipole antennas) Frequency range : 327 MHz Instantaneous bandwidth : 10 MHz Continuum and spectrum modes Dual polarization Field of view : ~(1 rad) 2 or (10 deg.) 2 depending on observation mode Beam size (angular resolution) : ~15 Effective collecting area : ~ 700 m 2 Receiver temperature : ~100 K Point source sensitivity : seconds integration Time resolution : 1ms or less Observing modes – Phased array mode for solar wind monitoring – Interferometer mode for radio sky imaging – Both modes for variable objects 5

6 Tile (Antenna + Reflector) Reflecting plane can be rotated along N-S direction to increase the sky coverage 6

8 Staffs for Model run Total 8 staffs working for ENLIL and IPS model run (4 operators designated to model running and forecasting) Forecasting Division Model Operator Lee, J.H. Kwon, H.J. Park, S.R. Yun, J.H. ENLIL and IPS model run / forecast

9 IPS MODEL

10 History Collboration Jeju IPS meeting (2012, 04. KSWC) DR. Jackson (UCSD), Dr. Tokumaru, Dr. Kojima (Nagoya Univ.) Introduce KSWC and facilities, discuss international collaboration UCSD agreement Agreement with UCSD for IPS model introduction to KSWC ( ) Based on the agreement, test of the IPS model starts for operational introduction in 2013 Nagoya. Uni. agreement Agreement with STELAB (Nagoya Univ.) for IPS research collaboration ( ) Data exchange, collaborative research More Collboration Prof. Manoharan from Ooty, India visit KSWC ( ) and discuss the collaboration Discuss the possible collaboration with MEXART (Mexico)

11 IPS international collaboration US IPS model US IPS model India (Ooty) India (Ooty) Mexico (MEXART) Mexico (MEXART) Japan (STELAB) Japan (STELAB) Korea (KSWC) Korea (KSWC) MOU ( ) Model implementation MOU ( ) Data and research collaboration Model and Data IPS data Solar wind/CME research -International collaboration with IPS model (UCSD) and observational data

15 KSWC IPS model output - Run the IPS model everyday at 02:00 UT (11:00 KST) Enlarge with animation

16 RECENT WORKS WITH MODELS

17 IPS model Standard IPS input data format for model run (Japan, Korea ) p IPS_JEJU 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 dataSTELAB + KSWC data

18 Compare the result of ENLIL & IPS Synchronize the model output results and compare two models 7 days (-2/+5) prediction results, 6 hours cadence

20 Summary KSWC have been operating two solar wind prediction models from 2013 ENLIL with CONEIPS Start of model run at KSWC Jan, 2013May, 2013 DeveloperDr. Dusan OdstricilDr. Bernard V. Jackson Computing infra2 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) Input dataWSA with CME parameterIPS observation, NSO magnetogram Output resultsTime cadence images and plots ServiceProvide forecast result in animation via WEB (www.spaceweatehr.go.kr) Manpower 8 people ( 4 staffs and 4 operators)

21 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
