Assessment of GRAS Ionospheric Measurements for Ionospheric Model Assimilation
Remote Sensing, 2023 We conducted a study to assess the GNSS (Global Navigation Satellite System) Receiver for Atmospheric Sounding (GRAS) ionospheric data quality by processing Radio Occultation (RO) observations of ionospheric products. The main objective of the study is to validate ionospheric data generated at EUMETSAT, such as ionospheric bending angle profiles ...

Investigation of the Earth Ionosphere using the Radio Emission of Pulsars [PDF]
, 2013 The investigation of the Earth ionosphere both in a quiet and a disturbed states is still desirable. Despite recent progress in its modeling and in estimating the electron concentration along the line of sight by GPS signals, the impact of the disturbed ...

, 2018 This chapter summarizes our current understanding of the ionosphere of Saturn. We give an overview of Saturn ionospheric science from the Voyager era to the present, with a focus on the wealth of new data and discoveries enabled by Cassini, including a massive increase in the number of electron density altitude profiles.

Ionospheric imaging in Africa [PDF]
Radio Science, 2014 Accurate ionospheric specification is necessary for improving human activities such as radar detection, navigation, and Earth observation. This is of particular importance in Africa, where strong plasma density gradients exist due to the equatorial ionization anomaly. In this paper the accuracy of three-dimensional ionospheric images is assessed over a

Operative center of the geophysical prognosis in Izmiran [PDF]
Annales Geophysicae, 2005 IZMIRAN was founded about 65 years ago with one of the goals of carrying out geomagnetic prognoses. More or less, this activity has been developed during its entire history, but about 6 years ago this aim became sufficiently feasible due to the ...

An ionospheric index suitable for estimating the degree of ionospheric perturbations [PDF]
Journal of Space Weather and Space Climate, 2018 Space weather can strongly affect trans-ionospheric radio signals depending on the used frequency. In order to assess the strength of a space weather event from its origin at the sun towards its impact on the ionosphere a number of physical quantities need to be derived from scientific measurements.

Deformation of Ionospheric Potential Pattern by Ionospheric Hall Polarization [PDF]
Journal of Geophysical Research: Space Physics, 2019 AbstractThe present study shows that the ionospheric Hall polarization can deform the high‐latitude ionospheric convection field, which is widely considered to be a manifestation of the convection field in the magnetosphere. We perform the Hall polarization field separation with a potential solver by changing the conductance distribution step by step ...
