Being able to predict (forecast and nowcast) the extreme events and develop the strategy for mitigation vital as the space assets and critical infrastructures, such as communication and navigation systems, power grids, and aviation, are all extremely sensitive to the external environment. Post-event analysis is crucially important for the development and maintenance of numerical models, which can predict extreme SW events to avoid failure of the critical infrastructures. </i></div><div class=""><i class=""><br class=""></i></div><div class=""><i class="">This session aims to address both the current state of the art of SW products and new ideas and developments that can enhance the understanding of SW and SC and their impact on critical infrastructure. We invite presentations on various SW and SC-related activities in the Sun-Earth system: forecast and nowcast products and services; satellite observations; model development, validation, and verification; data assimilation; development and production of geomagnetic and ionospheric indices. Talks on SW effects on applications (e.g. on airlines, pipelines and power grids, space flights, auroral tourism, etc.) in the Earthโs environment are also welcomed.</i></div><div class=""><br class=""></div><div class="">We look forward to receiving your contributions and thank you very much for your attention.</div><div class=""><br class=""></div><div class="">Sincerely yours, session conveners,</div><div class="">Guram Kervalishvili,</div><div class="">Yulia Bogdanova,</div><div class="">Claudia Borries,</div><div class="">Therese Moretto Jorgensen,</div><div class="">Alan Thomson</div><div class=""><div class="" style="word-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;"></div></div><div class="">
