Description: While satellites can provide a range of both solar and heliospheric remote-sensing observations as well as in-situ measurements of many detailed plasma parameters important to the understanding of physical processes at the Sun and in the solar wind, magnetosphere, and ionosphere, the many ground-based networks of instruments provide crucial background information on the temporal and spatial context of the satellite observations, and also provide the only means to monitor the response of the global system in terms of energy content and dynamics of the involved global current systems, particle populations, and impacts on the neutral atmosphere. Ground-based observations and measurements enable data sets that are difficult or expensive to reliably obtain from space, e.g. solar radio arrays or large-aperture telescopes, and provide many observations with higher cadence and data latency than space-based platforms. We invite presentations on traditional or novel approaches for the use of combined ground-based and satellite data for the benefit of space weather science, monitoring or predictions. The range of topics spans from the use of global indices for space weather modelling to the more local coordination of satellite and ground-based observations along the same magnetic field line, or along similar latitudes or L-shells for terrestrial analyses, or for solar and heliospheric in-situ/remote-sensing model-data coordination in support of space weather research and prediction. We also invite presentations addressing successes or difficulties in creating and maintaining ground-based instrumentation and observing networks, the provision of coordinated datasets and other important issues of ground-based observations in support of space weather modelling and operations. While satellite missions often are provided through national and global strategies, with support from international space agencies, ground-based networks are often provided and maintained based on individual or institutional efforts and coordinated on a rather ad-hoc basis. We also invite presentations with insights in best practices for international coordination of ground-based assets in space science and space weather.

Description: Space weather events have caused disruptions to aviation communications, navigation and surveillance systems, and increased radiation exposure at aircraft cruising levels in a non-acute fashion. The aviation industry is becoming increasingly aware of these impacts. On 7th November 2019, the International Civil Aviation Organization (ICAO) launched a real-time worldwide space weather service for aviation. Currently, four global centers provide the service, issuing advisories in case of space weather events with potential impacts on aviation. The service targets three broad space weather impact areas: High-Frequency Communications, GNSS-based navigation and surveillance and increased radiation aboard aircraft. Satellite communications have been identified at this point as a fourth impact area, but have not yet been implemented. The ICAO service started when the solar activity was low, but the recent increase (ascending phase of solar cycle 25) raises the need for mature, qualitatively good, possibly validated, and harmonized advisories to further improve the safety and operations of the aviation system against more intense solar events. For this last reason, it is important to draw conclusions not only on the past effort on validations, comparisons, and harmonization activities but also on specifications as currently defined for the ICAO service. Integration of additional observations and models that are aligned with the aviation needs (including satellite communication) would contribute to improvements of the service. This session aims to give an update on the ongoing efforts, and to sketch plans for future activities in order to bridge the gap between science of space weather impacts and its translation into the needs of the aviation industry. In this regard, feedback from the aviation community is particularly welcomed. We encourage contributions from researchers and engineers working on the various impacts of space weather on aviation, solutions/mitigations for these impacts on aviation, as well as providers and users of current space weather services for aviation.

Description: New Space philosophy, which is underpinned by novel and innovative satellite development concepts, has generated keen interest. It is therefore a timely opportunity for hosting space weather instruments and for dedicating smallsat missions (from Cubesats to Nanosats) to space weather monitoring. These new developments enable innovative architectures and opportunities for new actors, towards provision of extensive space weather data. The relatively low cost of these satellites, as well as their simplified instrument-to-platform interfacing, allows the possibility of launching large constellations of complementary space weather instruments and of performing multi-point measurements. Subsequently, these new mission architectures generate new data models and policy, as highlighted by the D3S missions from ESA and by the SPIRE constellation. This current popularity, along with increasing solar activity and the resulting enhanced risk of onboard anomalies, raises the question as to how to further advance space weather monitoring and awareness, to the next level. We propose in this session to address these questions at system, data and payload levels, and to encourage discussion on potential future benefits to space weather monitoring through the use of smallsats. We will especially address funding mechanisms and business development plans for current projects by agencies, academia and industry, and also for potential future collaborations between different spaceborne actors.
