<b>G08 Ionospheric Space Weather</b><br>
<br>
***********************************************<br>
<b>Description</b>:<br>
This session will focus on the ionospheric and space weather events that may impact telecommunications and navigation systems. It will also cover all areas of ionospheric space weather research including modeling, data assimilation, and novel observations,
especially those using radio wave techniques. Of special interest are papers describing the assessment and validation of space weather models, and the justification of the need for new ground and space-borne measurements. Studies and investigations addressing
the modeling, forecasting and/or mitigation of ionospheric phenomena due to space weather events, such as large scale ionospheric gradients or medium- and small-scale irregularities, are also welcome.<o:p></o:p></span></p>
