[PEM15-04] Development of MAGDAS project: Search for global electromagnetic coupling from polar to equatorial ionosphere
Keywords:global electromagnetic coupling, Pc2 pulsation, Magnetosphere-ionosphere Coupling
The MAGDAS project investigates such a global electromagnetic coupling system by combining global geomagnetic field network observation with electric field observation using ionosonde installed at low and dip-equator region.
Recently, by using 250Hz sampling and 10Hz averaged MAGDAS 9 magnetometer data, we found that when the auroral substorm were enhanced during geomagnetic storm, together with enhancement of Pc1 wave at the polar region, the global Pc2 type disturbances (period range from 5 to 20 sec) can be captured from polar to equatorial region. In this talk, we will present recent update of MAGDAS project and of which scientific results.
