Being able to predict (forecast and nowcast) the extreme events and develop the strategy for mitigation 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 space weather events in order to avoid failure of the critical infrastructures. </em></div><div style="color: rgb(14, 16, 26); margin-top: 0pt; margin-bottom: 0pt;" class=""><br class=""></div><div style="color: rgb(14, 16, 26); margin-top: 0pt; margin-bottom: 0pt;" class=""><em style="margin-top: 0pt; margin-bottom: 0pt;" class="">This session aims to address both the current state of the art of space weather products and new ideas and developments that can enhance the understanding of space weather and space climate and its impact on critical infrastructure. We invite presentations on various space weather and space climate-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 space weather 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></div><div style="color: rgb(14, 16, 26); margin-top: 0pt; margin-bottom: 0pt;" class=""><br class=""></div><div style="color: rgb(14, 16, 26); margin-top: 0pt; margin-bottom: 0pt;" class=""><strong style="margin-top: 0pt; margin-bottom: 0pt;" class="">Confirmed invited speaker:</strong><span data-preserver-spaces="true" style="margin-top: 0pt; margin-bottom: 0pt;" class=""> Claudia Stolle (GFZ German Research Centre for Geosciences) will give a talk on "Observing Earth space environment with LEO multi-mission data”.</span></div><div style="color: rgb(14, 16, 26); margin-top: 0pt; margin-bottom: 0pt;" class=""><br class=""></div><div style="color: rgb(14, 16, 26); margin-top: 0pt; margin-bottom: 0pt;" class=""><span data-preserver-spaces="true" style="margin-top: 0pt; margin-bottom: 0pt;" class="">We look forward to receiving your contributions and thank you very much for your attention.</span></div><div style="color: rgb(14, 16, 26); margin-top: 0pt; margin-bottom: 0pt;" class=""><br class=""></div><div style="color: rgb(14, 16, 26); margin-top: 0pt; margin-bottom: 0pt;" class=""><span data-preserver-spaces="true" style="margin-top: 0pt; margin-bottom: 0pt;" class="">Sincerely yours, session conveners,</span></div><div style="color: rgb(14, 16, 26); margin-top: 0pt; margin-bottom: 0pt;" class=""><span data-preserver-spaces="true" style="margin-top: 0pt; margin-bottom: 0pt;" class="">Guram Kervalishvili,</span></div><div style="color: rgb(14, 16, 26); margin-top: 0pt; margin-bottom: 0pt;" class=""><span data-preserver-spaces="true" style="margin-top: 0pt; margin-bottom: 0pt;" class="">Yulia Bogdanova,</span></div><div style="color: rgb(14, 16, 26); margin-top: 0pt; margin-bottom: 0pt;" class=""><span data-preserver-spaces="true" style="margin-top: 0pt; margin-bottom: 0pt;" class="">Claudia Borries,</span></div><div style="color: rgb(14, 16, 26); margin-top: 0pt; margin-bottom: 0pt;" class=""><span data-preserver-spaces="true" style="margin-top: 0pt; margin-bottom: 0pt;" class="">Therese Moretto Jorgensen,</span></div><div style="color: rgb(14, 16, 26); margin-top: 0pt; margin-bottom: 0pt;" class=""><span data-preserver-spaces="true" style="margin-top: 0pt; margin-bottom: 0pt;" class="">Alan Thomson</span></div><div style="color: rgb(14, 16, 26); margin-top: 0pt; margin-bottom: 0pt;" class=""><br class=""></div><div style="color: rgb(14, 16, 26); margin-top: 0pt; margin-bottom: 0pt;" class=""><span data-preserver-spaces="true" style="margin-top: 0pt; margin-bottom: 0pt;" class="">P.S.
