Web24 mrt. 2024 · Lack of instrument sensitivity to low electron density (Ne) concentration makes it difficult to measure sharp Ne vertical gradients (four orders of magnitude over 30 km) in the D/E-region. A robust algorithm is developed to retrieve global D/E-region Ne from the high-rate GNSS radio occultation (RO) data, to improve spatio-temporal coverage … WebSince scintillations are an indicator for the presence of irregularities of electron density in the ionosphere, the scintillation measurements are used to determine the spatial and temporal distribution of the ionospheric irregularities.

Web25 mrt. 2024 · Variability in electron density values is greater at dawn than at dusk. Radio Occultation Science Experiment (ROSE) and Langmuir Probe and Waves (LPW) electron density values agree well on duskside. At dusk, differences between ROSE and LPW electron densities imply that the systematic errors of these instruments are smaller than … Web30 okt. 2024 · Ionospheric irregularities occur near the geomagnetic equator after sunset and multiple studies have observed the extension of irregularity occurrence after midnight (e.g., Dao et al. 2011; Huang et al. 2014).They may be seen as field-aligned structures characterized by plasma density depletions, observed by satellites and radar … Web18 mei 2011 · Ionospheric electron density observed by FORMOSAT-3/COSMIC over the European region and validated by ionosonde data Andrzej Krankowski, Irina Zakharenkova, Anna Krypiak-Gregorczyk, Irk I.
