The topic will cover the wide range of the aspects of solar-terrestrial physics that deal with the effects of space phenomena on different levels of geo-space. Effects range from those observed on spacecraft related activities all the way down to Earth and to other Solar System bodies, including impacts on technological systems, human health and life in space, as well as Earth`s climate. We welcome theoretical, observational, as well as applied contributions (effects on terrestrial and geo-space environments) on all aspects of Space Weather. Special emphasis will be put on new multi-diagnostics data base and services and on construction of relevant roadmap for future Space Weather products, improvement of forecasting models, application for Space geodetic techniques such as GNSS(ground-and satellite-based), DORIS, VLBI, satellite altimetry or the GPS radio occultation missions, applications for GICs prediction, as well as contributions related to the ESA Space Situational Awareness (SSA). This session aims at merging new and existing methods of observations and diagnostics of Solar System habitats and Space Weather services, as LOFAR radio diagnostics and new investigation and application for incoming ESA exploration missions like JUICE and SOLAR ORBITER.
