The ESWW plenary sessions form a key component of the conference. They are designed to be open to all attendees with more-overarching themes of interest to the wider space-weather community. This year, we based the four plenary sessions on the responses to the 2020 call with the addition of an invited COVID-related session which the Programme Committee thought was very timely. The full description of these sessions can be seen below and at the bottom of the page is the link to start your abstract submission.
For work to be considered for presentation in one of the plenary sessions authors must submit a short abstract (2-3 paragraphs) with a title and list of authors, select the plenary session in which they wish to present, and select whether they would like an oral or poster. The session abstracts should be read carefully as submission to the wrong session will negatively impact the chances of selection (even though the PC will do their best to move mis-assigned abstracts). The length and number of oral presentations will be assigned at the discretion of the session Chairs and PC members. Posters/Quick Views will be assigned a board (for the in-person component) on which the poster can be found any time during ESWW. For those joining online, Quick Views will be implemented. Finally, in conjunction with the Convenors, the PC reserves the right to make one or more plenary sessions in an alternative format, such as having a panel/Q&A/discussion format rather than just a series of oral presentations for the live/hybrid/in-person part of the ESWW2021/ESWW17.
ESWW2021 will have 4 plenary session themes:
Space Weather preparedness, risk, policy, and strategy in light of the Coronavirus Pandemic
Space weather can have far-reaching effects on our complex and highly interconnected societal infrastructure. Impacts to satellite and airline operations, communications networks, navigation systems including GNSS, and national power grids, can have significant consequences on economic and security interests worldwide. Consequently, the potential impacts of, and government preparedness for, space weather events is attracting the attention of government leadership in many countries and is driving needs for new and improved space weather services. Operational space weather forecasting capabilities, products, and services have become a focus of scientific research and development efforts. We have seen a shift from mostly basic research of space weather phenomena to more applied research focused on space weather forecasting needs.
Having said all that, the widespread, disruptive and damaging effects of the Covid-19 pandemic may lead to considerable impacts on the developments detailed above. For example, some countries may now view space weather as a less serious risk, while on the other hand, changes in social behaviour as a result of the pandemic (eg increased use of contactless payment transactions) may mean others consider the space weather risk to be even more important. We propose this plenary session to highlight the policy efforts currently underway worldwide to prepare societies for extreme space weather events, and to discuss how these activities have been affected by the Covid-19 pandemic. We invite abstract submissions to showcase plans, policies, and strategies that improve our ability to prepare for, mitigate, respond to, and recover from the potentially devastating impacts of space weather events, and which highlight the impact of Covid-19 on these activities.
Novel radio diagnostics for science operational space weather service applications
Radio wave instruments on-board spacecraft together with ground-based radio observatories are key tools for diagnostic the local space plasma properties. These radio observations may be used to derive accurate empirical inputs for forecasting models and operational space weather services tools.
In particular, solar flares, eruptive prominences, CMEs, ionospheric disturbances, and Solar Wind streams may emit radio waves and/or interact with radio waves. The resulting radio emission can be used as proxy in now-casting and/or forecasting activities.
Radio observations contribute to a large variety of diagnostics ranging from the ionosphere to the heliosphere and the Sun. The Radio instruments considered in this framework include facilities such as LOFAR, space-based missions like Parker Solar Probe and Solar Orbiter, and ultimately, novel radio facilities such as the Square Kilometer Array (SKA) and new space borne satellite interferometry.
This session is aimed at presenting the state-of-the-art of radio diagnostics possibilities and techniques and to discuss the operational scenarios of radio instruments for Space Weather. Special attention will be given to the required Space Weather services and to the contribute of the existing and forthcoming new facilities. These include the mission concept of an interferometer in space, made by a constellation of small spacecraft designed to localise and track the radio emission in the heliosphere.
The ionosphere is a complex coupled system that affects a wide range of trans-ionospheric and sub-ionospheric radio frequency (RF) systems operating below approximately 2 GHz. These systems include satellite communications, GNSS, space-based radars and space situational awareness radars. There is increasing recognition of this topic across Europe; for example, in the UK it will form an important part of the Space Weather Instrumentation, Measurement, Modelling and Risk (SWIMMR) project. This will address issues of transitioning research to operations, and of providing robust and continuous verification of products.
We shall convene a plenary session on ionospheric effects covering aspects of ionospheric measurement, modelling, and mitigation applicable to the wide range of impacted RF systems. The session shall include a panel discussion in order to foster dialogue between scientists, service providers and users, and to provide a more informal forum for discussion and dissemination of SWIMMR, and other, activities.
The effect of Space Weather on established operational systems such as large geostationary communications & meteorological satellites and ESA / NASA Science Missions has been a popular topic in previous European Space Weather Week conferences, where there has been considerable focus on maintaining robust space environment specifications whilst taking into account evolving scientific understanding of Solar Physics and Near-Earth Space processes.
This session will focus for the first time on the effect of Space Weather on the emerging Mega-Constellations of small satellites such as Planet, Spire, OneWeb, Starlink and Telesat-LEO. We invite researchers, service providers and constellation designers / manufacturers / operators to provide their thoughts on the impact of Space Weather on the operations and services provided by these constellations:
The Session will include a Discussion Panel to allow conversation between Stakeholders and finally questions from the audience.
