Ionospheric Electron Density Model by Electron Density Grid Deep Neural Network (EDG-DNN)

open access: yesAtmosphere, 2023
Electron density (or electron concentration) is a critical metric for characterizing the ionosphere’s mobility. Shortwave technologies, remote sensing systems, and satellite communications—all rely on precise estimations of electron density in the ...

Auroral E-region electron density gradients measured [PDF]

open access: yesAnnales Geophysicae, 2000
In the theory of E-region plasma instabilities, the ambient electric field and electron density gradient are both included in the same dispersion relation as the key parameters that provide the energy for the generation and growth of electrostatic ...

Pseudopotentials from electron density [PDF]

open access: yesPhysical Review A, 1996
A method is introduced that allows the construction of pseudopotentials in the density-functional theory. This method is based on a procedure worked out by one of the authors [J. Phys. B 26, 43 (1993); Philos. Mag. B 69, 779 (1994)] for determining Kohn-Sham potentials, one-electron orbitals, and energies from the electron density.

The Comparison of Electron Density between CSES In Situ and Ground-Based Observations in China

open access: yesRemote Sensing, 2022
As the observation accuracy of parameters in the ionosphere cannot be directly checked, the comparison with other observations is the main way to evaluate the data quality of satellite measurements.

Spectroscopic Characterization of a Pulsed Low-Current High-Voltage Discharge Operated at Atmospheric Pressure

open access: yesApplied Sciences, 2022
The advantages of pulsed low-current high-voltage discharges operated at atmospheric pressure and the ease with which such discharges can be implemented industrially contributed to their popularity. However, the high reactivity of a pulsed plasma implies
