Global ionospheric maps with a high temporal resolution

Results in Physics, 2020
A new approach is proposed for the global ionospheric modeling using epoch-by-epoch estimation. The GIMs with a high temporal resolution are greatly useful for studying the climatology and weather of the ionosphere, including ionospheric variations, such

Possible Atmosphere and Ionospheric Anomalies of the 2019 Pakistan Earthquake Using Statistical and Machine Learning Procedures on MODIS LST, GPS TEC, and GIM TEC

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
Identifying atmospheric and ionospheric anomalies based on remote sensing satellites has contributed highly to develop the hypothesis of lithosphere-atmosphere-ionosphere coupling over the earthquake (EQ) epicenter during the seismic preparation period ...

Ion composition and drift observations in the nighttime equatorial ionosphere [PDF]

Journal of Geophysical Research, 1974
The first in situ measurements of ion composition in the nighttime equatorial E and F region ionospheres (90-300 km) are presented and discussed. These profiles were obtained by two rocket-borne ion mass spectrometers launched from Thumba, India on March 9-10, 1970 at solar zenith angles of 112 deg and 165 deg.

Modeling the Topside Ionosphere Effective Scale Height through In Situ Electron Density Observations by Low-Earth-Orbit Satellites

Universe, 2023
In this work, we aim to characterize the effective scale height at the ionosphere F2-layer peak (H0) by using in situ electron density (Ne) observations by Langmuir Probes (LPs) onboard the China Seismo-Electromagnetic Satellite (CSES—01).

Empirical Parameterizations of ULF Power and Drift Orbit Averaged Radial Diffusion Coefficients From Ground Magnetometers for Different MLT

Earth and Space Science, Volume 13, Issue 11, November 2026.
Abstract Radial diffusion, driven by ultra‐low frequency (ULF) waves, is an important process for the transport of electrons in the outer radiation belt. Ground magnetometers give us constant observations of such ULF waves but their usefulness is limited by the models used to transform ground measurements into their progenitor fields in space.
