A new method for reconstruction of the vertical electron density distribution in the upper ionosphere and plasmasphere

Abstract: [1] Ground-based ionosphere sounding measurements alone are incapable of reliably modeling the topside electron density distribution above the F layer peak density height. Such information can be derived from Global Positioning System (GPS)-based total electron content (TEC) measurements. A novel technique is presented for retrieving the electron density height profile from three types of measurements: ionosonde ( f o F 2 , f o E, M 3000 F 2 , h m f 2 ), TEC (GPS-based), and O + -H + ion transition level.

“…It is well accepted (see, for example, Banks & Kockards 1973;Stankov et al 2003) that the broad maximum of the vertical H + distribution is placed slightly above the transition O + -H + height, e.g. above the transition region with the highest rate of charge-exchange reaction OMH + .…”

“…Indeed, the behavior of the light ion density in the topside F region and the plasmasphere has been extensively studied by satellite data and in general, the main physics is known. Since Moffett & Hanson (1973) have proposed excessive He + ions at low latitudes as formed through the E · B drift at equator, several basic studies have been conducted to reveal He + distribution, among them Heelis et al (1990), Kutiev & Stankov (1994), and recently Su et al (2005). The blue curve represents the expected light-ion (H + + He + ) distribution.…”

“…One possible way to reconstruct the topside electron density profile is to make use of the analytical functions. During the past few decades, many mathematical functions such as the Chapman, exponential, parabolic and Epstein functions have been used to describe the ionospheric height profiles (Booker, 1977;Rawer et al, 1985;Di Giovanni and Radicella, 1990;Stankov et al, 2003;Reinisch et al, 2004;Bilitza et al, 2006).…”

“…H T is the scale height, which is an unknown parameter. An important and inherent parameter for the mathematical functions that largely determine the shape of the electron density profile is the ionospheric scale height Stankov et al, 2003;Belehaki et al, 2006). The ionospheric scale height measures the shape of the electron density profile, indicates the gradient of electron density, and intrinsically connects to ionospheric dynamics, plasma temperature and compositions.…”

“…The system, dubbed LIEDR (Local Ionospheric Electron Density profile Reconstruction), acquires and processes in real time the concurrent and collocated groundbased TEC and digital ionosonde measurements, and ultimately, deduces a full-height electron density profile based on a reconstruction technique proposed by Stankov et al (2003). In this way, the topside profile is more adequately represented because of the use of additional information about the topside ionosphere, such as TEC and O + /H + ion transition height.…”
