Space weather and space climate are collective terms that describe the Sun-Earth system on timescales varying between minutes and decades and include processes at the Sun, in the heliosphere, magnetosphere, ionosphere, thermosphere and at the lower atmosphere. Being able to predict (forecast and nowcast) the extreme events and develop the strategy for mitigation are dramatically important because space assets and critical infrastructures in the EU, 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.
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.
