An empirical topside electron density model for calculation of absolute ion densities in IRI

An empirical model of the electron density in the topside ionosphere for solar maximum and minimum is introduced. This model is intended for use in combination satellites for high solar activity. Examples of vertical pr...

Variation of the electron density in the high-latitude topside ionosphere during large magnetic storms

We investigate the response of the high-latitude topside ionosphere to large geomagnetic storms. For our study we employ electron-density profiles, derived from the Alouette and ISIS topside sounder satell...

High-Latitude Topside Ionospheric Vertical Electron-Density-Profile Changes in Response to Large Magnetic Storms

topside vertical electron-density profiles Ne(h). Ten large magnetic storms (with Dst less than -100 nT) were identified that satisfied both the Ne(h) profile and the solar-wind data constraints. During f...
