Prediction of the extreme events (forecast and nowcast) and development of the mitigation strategy are 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. </em></p><p style="color: rgb(14, 16, 26); margin-top: 0pt; margin-bottom: 0pt;"><br></p><p style="color: rgb(14, 16, 26); margin-top: 0pt; margin-bottom: 0pt;"><em style="margin-top: 0pt; margin-bottom: 0pt;">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 Earth’s environment are also welcomed.</em></p><p style="color: rgb(14, 16, 26); margin-top: 0pt; margin-bottom: 0pt;"><br></p><p style="color: rgb(14, 16, 26); margin-top: 0pt; margin-bottom: 0pt;"><br></p><p style="color: rgb(14, 16, 26); margin-top: 0pt; margin-bottom: 0pt;"><strong style="margin-top: 0pt; margin-bottom: 0pt;">Confirmed invited speaker</strong><span data-preserver-spaces="true" style="margin-top: 0pt; margin-bottom: 0pt;"> Matt Taylor (ESTEC, European Space Agency) will speak about the cross-discipline approach to examine the physical links between Weather in Space and the Lower Atmosphere.</span></p><p style="color: rgb(14, 16, 26); margin-top: 0pt; margin-bottom: 0pt;"><br></p><p style="color: rgb(14, 16, 26); margin-top: 0pt; margin-bottom: 0pt;"><span data-preserver-spaces="true" style="margin-top: 0pt; margin-bottom: 0pt;">We look forward to receiving your contributions and thank you very much for your attention.</span></p><p style="color: rgb(14, 16, 26); margin-top: 0pt; margin-bottom: 0pt;"><br></p><p style="color: rgb(14, 16, 26); margin-top: 0pt; margin-bottom: 0pt;"><span data-preserver-spaces="true" style="margin-top: 0pt; margin-bottom: 0pt;">Sincerely yours, session conveners,</span></p><p style="color: rgb(14, 16, 26); margin-top: 0pt; margin-bottom: 0pt;"><span data-preserver-spaces="true" style="margin-top: 0pt; margin-bottom: 0pt;">Guram Kervalishvili,</span></p><p style="color: rgb(14, 16, 26); margin-top: 0pt; margin-bottom: 0pt;"><span data-preserver-spaces="true" style="margin-top: 0pt; margin-bottom: 0pt;">Yulia Bogdanova,</span></p><p style="color: rgb(14, 16, 26); margin-top: 0pt; margin-bottom: 0pt;"><span data-preserver-spaces="true" style="margin-top: 0pt; margin-bottom: 0pt;">Therese Moretto Jorgensen,</span></p><p style="color: rgb(14, 16, 26); margin-top: 0pt; margin-bottom: 0pt;"><span data-preserver-spaces="true" style="margin-top: 0pt; margin-bottom: 0pt;">Claudia Borries</span></p><div>
