A density-temperature description of the outer electron radiation belt during geomagnetic storms [PDF]
, 2010 Bi-Maxwellian fits are made to energetic-electron flux measurements from seven satellites in geosynchronous orbit, yielding a number density (n) and temperature (T) description of the outer electron radiation belt.

A coordinated ground-based and IMAGE satellite study of quiet-time plasmaspheric density profiles [PDF]
, 2003 Cold plasma mass density profiles in the plasmasphere have been determined for the geomagnetically quiet day of 19th August 2000 using the cross-phase technique applied to ground-based magnetometer data from the SAMNET, IMAGE and BGS magnetometer arrays.

Annals of Geophysics, 1995 Tests of the analytical model of the electron density profile originally proposed by G, Di Giovanni and S.M. Radicella (DGR model) have shown the need to introduce improvements in order to obtain a model able to reproduce the ionosphere in a larger ...

Electron Density Profile Measurements on LHD
IEEE Transactions on Plasma Science, 2003 Several kinds of density diagnostics have been developed and routinely operated to provide density profile information on the Large Helical Device. A 13-channel far-infrared laser interferometer and a two-color millimeter-wave interferometer are used for monitoring the density profile.

Interfacing between regional and global, electron density height profile
Annals of Geophysics, 1996 A first analysis of the possibility of interfacing regional and global electron density height profile models, over a buffer zone, was performed considering the results obtained using different models such as IRI 90 (Bilitza, 1990), DGR (Di Giovanni et ...

Relationships between electron density, height and sub-peak ionospheric thickness in the night equatorial ionosphere [PDF]
Annales Geophysicae, 2006 The development and decay of the southern equatorial anomaly night-time peak in electron density as seen at a number of ionosonde reflection points extending from New Guinea and Indonesia into northern Australia was examined in terms of the ...

The F1 ledge: density, height and slope
Annals of Geophysics, 1996 Diurnal variations of the F1 region ionization at 170 km altitude and the slope ?170 = dN/dh at this height are analyzed for mid-latitude and equatorial stations: Millstone Hill, Ramey, Puerto Madryn and Jicamarca. Both the density N(t) and the slope ?(t)

Underdense plasma lens with a transverse density gradient
Physical Review Accelerators and Beams, 2023 We explore the implications of a transverse density gradient on the performance of an underdense plasma lens and nonlinear plasma-based accelerator. Transverse density gradients are unavoidable in plasma sources formed in the outflow of standard gas jets,
