Research Abstract

Two-dimensional maps of ionospheric total electron content(TEC), rate of TEC change index(ROTI), loss-of-lock on GPS signals were derived using GPS receiver networks in Japan and the world. Using these data, ionospheric disturbances such as TIDs and plasma bubbles and their effects on GNSS were statistically studied. We have started realtime two-dimensional GPS-TEC observation in Japan and detected clear concentric ionospheric waves after the 2011 Tohoku earthquake.
