As the first significant discovery of the space age, the Van Allen radiation belts were detected in 1958 by James Van Allen and were found to be comprised of an inner and outer belt extending up to 25,000 miles above Earth’s surface. In 2013, Dan Baker, a director of CU Boulder’s Laboratory for Atmospheric and Space Physics (LASP) has discovered an invisible shield some 7,200 miles above Earth that blocks so called “killer electrons,” which whip around the planet at near light speed and have been known to threaten astronauts, fry satellites and degrade space systems during intense solar storms. These killer electrons have been the most concerned factor in space weather community. Since the twin Van Allen Probes were launched by NASA in 2012, many interesting reports have been published, e.g., a third radiation belt or transient “storage ring” between the inner and outer Van Allen radiation belts was that seems to come and go with the intensity of space weather.
KASI has been operating the receiving antenna for downloading the space weather beacon data from VAP since 2012 and also constructed the space weather prediction center in 2007. In this talk, I present some new results on the Earth’s radiation belt observed by VAPs and report our accomplishment and current status on the space weather research.
