About the Center

We provide a variety of information and common sense related to the space propagation environment.


The Korean Space Weather Center (KSWC) of the National Radio Research Agency(RRA) is a government agency that is responsible for space weather research and operations of the Republic of Korea. Since its founding in 1966, RRA has carried out routine space weather research, such as monitoring solar activities, ionospheric disturbances, and geomagnetic disturbances, while also providing information services to the public as part of its mandate under Korea's radio communications act.

On 19 August 2011 the Korean government established a new branch of RRA, the Korean Space Weather Center, an organization dedicated to space weather forecasting. RRA/KSWC is Korea's official source for space weather alerts and warnings.

KSWC operates two ionospheric observatories, one in Icheon and one in Jeju, both of which are equipped with an ionospheric sounder and a total electron content (TEC) monitor. Magnetometers are located in Icheon, Jeju, and Gangnung. The data from these instruments help to characterize localized geophysical responses to solar activities, which can result in disruptions to radio communications. The instruments are complemented by two others housed in Ichon-a solar radio spectrograph (SRS), which monitors solar outbursts, and an F10.7 centimeter solar radio flux meter, which monitors trends in solar activity based on ultraviolet influx. All these data are available in real time at

To reinforce these observational capabilities, KSWC set up an interplanetary scintillation (IPS) array and a Radio Interference Measuring Set (RIMS) by the end of 2011. IPS monitors solar wind and coronal mass ejections (CMEs) from the ground, and RIMS detects solar radio flares and monitors solar radio noise, which can interfere with many different kinds of radio telecommunication systems. Further, by constructing a tracking station in Jeju Island, off Korea's southern coast, KSWC participated in the global tracking networks for current and upcoming solar wind satellite missions. Tracking these satellites enables scientists to collect solar wind data in real time and give a 1-hour advance warning of impending geomagnetic activity. The station is equipped with a 13-meter- long parabolic antenna and dual receivers for tracking NASA's Advanced Composition Explorer (ACE) spacecraft, which has been in orbit since 1997, and its scheduled successor, the Deep Space Climate Observatory (DSCOVR) satellite. The tracking station has began monitoring the skies over East Asia from the end of 2011.

As part of RRA's close partnership with SWPC, KSWC staff have been trained at NOAA's Space Weather Prediction Center (SWPC). To further fortify international cooperation, since April 2011 RRA has been a member of the World Meteorological Organization (WMO) Inter-programme Coordination Team on space Weather. From the end of 2011, RRA became a regional warning center of the International Space Environment Service (ISES).
