IONORING - Real-time Total Electron Content over Italy

by Upper Atmosphere Physics research group

The main goal of the IONORING (IONOspheric RING) project is to exploit data from the RING (Rete Integrata Nazionale GPS) network to obtain ionospheric Total Electron Content (TEC) maps with very fine spatial resolution (0.1°x0.1°, lat x long). These maps will be useful to support ionospheric error mitigation in precise positioning and to study the ionosphere morphology and dynamics during strong solar and geomagnetic storms affecting the mid-latitude ionosphere. This page reports the TEC maps generated in real-time every 10 minutes collecting data from about 40 RING stations.

Our first geomagnetic storm

By Claudio Cesaroni posted February 17, 2017

An unusual broad Coronal Hole (CH) appeared today on the  southern hemisphere of the Sun atmosphere. The Solar Wind flowing from this CH is causing intermittent  disturbances on the Earth's magnetic Field (see figure below, courtesy of NOAA-SWPC and Kyoto geomagnetic observatory). For more information on the ongoing geomagnetic storm see www.spaceweather.com  Perturbations on the geomagnetic field can induce disturbances in the mid-latitude ionosphere causing an ehnancment or a decrease on the Total Electron Content. Today, real-ime maps provided by IONORING showed an higjer TEC (reaching about 20 TECu in the southern Italy) with respect to the previous days at the same hour as a signature of the geomagnetic storm.

Upper-left panel of the figure shows the behaviour of the planetary K index (Kp) and Auroral Electrojet index (AE) from which the evolution of the geomagnetic storm can be argued. Rigth panel reports the TEC maps on 17 February at 13:50 UT and the bottom-left panels represent the TEC maps at the same hour during 14, 15 and 16 February.
