Looking for a proxy of the ionospheric turbulence with Swarm data

Abstract: The present work focuses on the analysis of the scaling features of electron density fluctuations in the mid- and high-latitude topside ionosphere under different conditions of geomagnetic activity. The aim is to understand whether it is possible to identify a proxy that may provide information on the properties of electron density fluctuations and on the possible physical mechanisms at their origin, as for instance, turbulence phenomena. So, we selected about 4 years (April 2014–February 2018) of 1 Hz electro… Show more

“…Here, we use the ability of the SF as a tool to characterize complex surfaces, particularly with nonuniformly sampled and nonperiodic data, using the measured phase values that form the ionospheric screens. 11,21,22 Of particular interest here is the capacity to detect deviations from linearity. We calculated the SFs using the baseline phase values, deduced from the station solutions.…”

“…The Quasi-Dipole latitude is estimated by (1) tracking up along realistic geomagnetic field lines (e.g., those from the International Geomagnetic Reference Field) from the spacecraft position to the equatorial plane, and (2) then tracking down along the idealized dipole field line to a reference altitude. This coordinate system is frequently used in LEO data analyses (e.g., de Michelis et al, 2021). Details of the coordinates are given in Laundal and Richmond (2017).…”

“…The ionospheric index named Rate Of change of electron Density Index (RODI, [9]) is derived from LPs in situ Ne observations, while the Rate Of change of Total electron content Index (ROTI, [10]) is calculated from nonlocal TEC observations. These two indices allowed identifying a large spectrum of Ne irregularities ranging from meters to hundreds of kilometers, particularly affecting the high [9,[11][12][13][14] and low [15][16][17][18] latitudes.…”
