Keywords:TEC monitoring system, dense GNSS receiver network, GEONET real-time data

We are operating an ionospheric total electron content (TEC) monitoring system using dense GNSS receiver networks on the NICT Science Cloud system. We have automatically collected more than 7000 ground-based GNSS receivers’ data in the world, and converted into two-dimensional TEC maps. High-resolution TEC maps are available in Japan, North America, and Europe, where GNSS receivers are densely deployed. These TEC maps and global TEC maps are available through the web site, http://seg-web.nict.go.jp/GPS/DRAWING-TEC. These high-resolution TEC maps make it possible to get a full view of 100-1000 km scale ionospheric disturbances. Recently, we developed a real-time TEC monitoring system by processing streaming data of GEONET, which is a ground-based GNSS receiver network in Japan provided by Geospatial Information Authority of Japan. TEC are calculated within a delay of several minutes.
