Abstract
Ionosphere is a dynamical system that shows a complex behaviour due to its nonlinear coupling with the solar wind-magnetosphere system from above and with the lower atmosphere from below. This complexity manifests itself on a largely varying range of spatial and temporal scales in the different ionospheric sectors.
We leverage on the Swarm constellation data, investigated with techniques for non-linear non-stationary signal, to investigate the statistical properties of each spatio/temporal scale revealed by ionospheric data recorded in situ, i.e. in the topside ionosphere.
Resonant modes in ionospheric and related helio-geophysical proxies identified through signal processing techniques, like the Iterative Filtering, allows speculating at a climatological level on the cause-effect mechanisms by investigating the lags and mutual interaction among the modes.
This work is within the framework of the Swarm Variability of Ionospheric Plasma (Swarm-VIP) project, funded by ESA in the “Swarm+4D-Ionosphere” framework (ESA Contract No. 4000130562/20/I-DT).
