Corona hole

SunspotFilaments• Automatic solar information retriever(Sunspot,corona hole and filaments) with signal
processing applied to the data observed by satellites with 1 hour cadence• Physical Parameters of sunspots(area, polarity ratio, # of neutral lines, neutral line roughness, etc.)• Flare Probability based on physical parameters• It is now freely available @ http://spaceweather.go.kr/assa• Also it has been provided to CCMC, NASA

Figure. Schematics of NMSC GNSS data collection system. GNSS observation data are collected via active orpassive FTP transfer to KMA’s FTP server in DMZ area and automatically transferred to GNSS-DATA server. The
collected data are transferred to GNSS-ANALYSIS server for derivation of PWV(Precipitable Water Vapor) and TEC.

Examples of Model R2O transition• Assimilated IRI using ionosonde dataobserved at Icheon and Jeju, operated byRRA• The model product is used for HF

frequency mapping service by RRA• Mid-to-low latitude Ionospheric model byCNU• Modified to add X-ray Flare effect• Implemented on SWx model test bed
system operated by KMA• Solar maximum prediction by SNU• Prediction of the solar cycle• Implemented on SWx model test bed inKMA

Perspective :What do we need in the future?

Data matters….

SIDC, Royal Observatory,Belgium

NGDC, NOAA

• Where can we find the data from the member institutes from AOSWA?
• Since the space weather needs are emerging in Asia-Oceania region,

Regional data rather than global data is essential specifically, for instance,
ionophspheric observation data with easy-to-acess interface.

• We’d like to suggest AOSWA data portal that collect and provide thespace weather data especially focusing on the observation by theAOSWA members with easy-to-use interface.

Switchingto Service-oriented approach• What’s the next stage for the space weather
service?

• Are representative institutes covering whole rangeof the needs from the public including potential
SWx customers?

• Now, it is time to adopt the service-oriented

approach to SWx product switching from thetechnology-oriented one to improve its quality andthe interaction between service provider andcustomers.
