Travelling Ionospheric Disturbances (TIDs) constitute a threat for operational systems for which the ionosphere is an essential part (i.e., radio systems) or for which the ionosphere is fundamentally a nuisance (i.e. GNSS based systems and applications). The overarching objective of TechTIDE is to design and test new viable TID impact mitigation strategies for the technologies affected by the TIDs and in close collaboration with operators of these technologies, to demonstrate the added value of the proposed mitigation techniques which are based on TechTIDE products. To achieve this main goal, it is necessary to address the following specific objectives: i. Improve understanding regarding the physical processes resulting in the formation of TIDs, and consequently to identify the drivers in the interplanetary medium, the magnetosphere and the atmosphere; ii. Define the impact of the TIDs on the space based navigation systems (mainly EGNOS services and N-RTK) and on ground-based HF communication and geolocation systems; iii. Develop improved methodologies, based on consortium partners’ algorithms, suitable to support for the first time the direct,real-time identification and tracking of TIDs over wide world regions; iv. Establish an operational system to issue warnings of the occurrence of TIDs over the region extending from Europe to South Africa, to estimate the parameters that specify the TID characteristics and the inferred perturbation, and provide all additional geophysical information to the users to help them assess the risks and to develop mitigation techniques, tailored to their applications; v. Work systematically with potential users to assess the functionality, reliability and efficiency of the TechTIDE services paving the way to its systematic exploitation from users and to its sustainable operation.

The Europlanet 2020 Research Infrastructure (EPN2020-RI) will address key scientific and technological challenges facing modern planetary science by providing open access to state-of-the-art research data, models and facilities across the European Research Area. Its Transnational Access activities will provide access to world-leading laboratory facilities that simulate conditions found on planetary bodies as well as specific analogue field sites for Mars, Europa and Titan. Its Virtual Access activities will make available the diverse datasets and visualisation tools needed for comparing and understanding planetary environments in the Solar System and beyond. By providing the underpinning facilities that European planetary scientists need to conduct their research, EPN2020-RI will create cooperation and effective synergies between its different components: space exploration, ground-based observations, laboratory and field experiments, numerical modelling, and technology. EPN2020-RI builds on the foundations of successful FP6 and FP7 Europlanet programmes that established the ‘Europlanet brand’ and built structures that will be used in the Networking Activities of EPN2020-RI to coordinate the European planetary science community’s research. It will disseminate its results to a wide range of stakeholders including industry, policy makers and, crucially, both the wider public and the next generation of researchers and opinion formers, now in education. As an Advanced Infrastructure we place particular emphasis on widening the participation of previously under-represented research communities and stakeholders. We will include new countries and Inclusiveness Member States, via workshops, team meetings, and personnel exchanges, to broaden/widen/expand and improve the scientific and innovation impact of the infrastructure. EPN2020-RI will therefore build a truly pan-European community that shares common goals, facilities, personnel, data and IP across national boundaries

It has been robustly demonstrated that variations in the circulation of the middle atmosphere influence weather and climate throughout the troposphere all the way to the Earth’s surface. A key part of the coupling between the troposphere and stratosphere occurs through the propagation and breaking of planetary-scale Rossby waves and gravity waves. Limited observation of the middle atmosphere and these waves in particular limits the ability to faithfully reproduce the dynamics of the middle atmosphere in numerical weather prediction and climate models. ARISE2 capitalizes upon the work of the EU-funded first ARISE project combining for the first time international networks with complementary technologies such as infrasound, lidar and airglow. This joint network provided advanced data products that started to be used as benchmarks for weather forecast models. The ARISE network also allows enhanced and detailed monitoring of other extreme events in the Earth system such as erupting volcanoes, magnetic storms, tornadoes and tropical thunderstorms. In order to improve the ability of the network to monitor atmospheric dynamics, ARISE2 proposes to extend i) the existing network coverage in Africa and the high latitudes, ii) the altitude range in the stratosphere and mesosphere, iii) the observation duration using routine observation modes, and to use complementary existing infrastructures and innovative instrumentations. Data will be collected over the long term to improve weather forecasting to monthly or seasonal timescales, to monitor atmospheric extreme events and climate change. Compared to the first ARISE project, ARISE2 focuses on the link between models and observations for future assimilation of data by operational weather forecasting models. Among the applications, ARISE2 proposes infrasound remote volcano monitoring to provide notifications to civil aviation. The data portal will provide high-quality data and advanced data products to a wide scientific community.
