A new dimension of access to ionospheric parameter estimation is emerging with the appearance of the new phased-array incoherent scatter radars, application of interferometric techniques in radio regime, sophisticated ionospheric modification experiments and build-up of large observational systems which provide real-time and unified data access utilizing an extensive set of various sensors.

This session welcomes papers on both local and large-scale processes in the ionosphere, magnetosphere-ionosphere-neutral atmosphere coupling, as well latitudinal couplings, advance in experimental and data analysis techniques, coordinated studies with multiple incoherent scatter radars, possibly also supporting space missions, progress on planning and prototyping new facilities such as EISCAT-3D, and coordination of observational systems, such as ESPAS. Contributions concerning techniques and systems in more application-oriented, service-type investigations, in support of radio systems and studies of space weather effects, are also welcome.
