Throughout the implementation of the project, extensive experience was gained in analyzing and processing Dynasonde data for TID studies, as well as in the complementary techniques that were employed and implemented, such as spectral analysis methods and statistical analysis techniques. The results obtained are at the forefront of the field, in particular those showing the correlation between geomagnetic activity and ionospheric variability in a statistical sense, for long periods of time characterized by only a small number of geomagnetic storms.
One of the unexpected products of this project was the large database of results describing TIDs detected using the Tromsø Dynasonde. This is intended as a resource for use in the study of AGW and TID activity by other scientists and interested parties. More than 200000 files were generated, containing different data types in .mat format. These will be available upon request, while sample files are hosted on the project website. These include the dynasonde data on a constant height grid, the results of the detrending procedure ((N_e ) ̅ and N_e^'), the results of the spectral analysis, and the wavevector components. Additionally, the catalogues of figures describing the characteristics of the dominant wave activity are available, with one figure per month for the time-domain data, the height stratified PSD and the distribution of the TID propagation parameters.
The work revealed that the solar-wind – magnetosphere – ionosphere coupling has a complex impact on the high-latitude thermosphere-ionosphere, influencing not just the background structure, composition and circulation, but also the small-scale structure through the generation of AGWs. This likely acts as an added source of energy and momentum, with a potential global impact as high-latitude AGWs propagate towards the middle and low-latitude sectors.
Regarding the broader impact for the general public, several public demonstrations and presentations were made in the past 2 years, involving interested scientists, young students or simply general audiences interested in science. Despite a great start in 2019, restrictions on public gatherings have made such events impossible in 2020 and very difficult in 2021. Nevertheless, the public interest has surpassed all expectations, particularly due to the availability of a in-house built Planeterrella experimental setup that functions as an invaluable illustrator of the solar wind-magnetosphere-ionosphere coupling. As soon as the pandemic situation sufficiently improves in Romania, a number of public demonstrations are already planned, involving several schools that would otherwise have difficulties participating in such events.
