Comparison of the topside ionosphere scale height determined by topside sounders model and bottomside digisonde profiles

Advances in Space Research, 2006
Topside ionospheric electron density extrapolation techniques rely on the applied profiler model with different techniques resulting in different profile shape. In all these techniques, the parameter that largely determines the shape of the profile is the scale height.

Modeling the daytime energy balance of the topside ionosphere at middle latitudes

Journal of Geophysical Research: Space Physics, 2017
AbstractRecently reported measurements from the Defense Meteorological Satellite Program (DMSP) indicate that the O+ temperature in the topside ionosphere is dependent on the fractional H+ density. This finding indicates that the mass‐dependent energy exchange rate between O+ and H+ plays an important role in the thermal balance of the topside ...

Model of topside ionosphere scale height based on topside sounder data

Advances in Space Research, 2006
Abstract A new model of topside ionosphere scale height is developed, based on the vertical electron density (Ne) profiles obtained from topside ionosondes. The model provides the vertical scale height (VSH) as a function of month of the year, local time, geomagnetic latitude, solar flux F107 and Kp index. To define VSH, the O+ scale height above the

ULF Waves in the Topside Ionosphere: Satellite Observations and Modeling

2011
Low-orbiting observations at satellites with high-accuracy magnetometers onboard (Oersted, CHAMP, ST5) have provided the possibility to examine the ULF wave (Pc3, Pi2, Pc1) structure in the topside ionosphere. Pc3 waves were detected very clearly in the compressional component of the satellite magnetic data, whereas on the ground, their signature was ...

Topside sounder model of scale height and transition height characteristics of the ionosphere

Advances in Space Research, 2007
Abstract The topside scale height (Ts) and transition height (Th) models, previously developed by the authors, provided Ts and Th for any set of input parameters: month, local time, geomagnetic latitude, solar flux F 107 , and Kp. It was found that the scale height and transition O + –H + height, extracted from each individual measured Ne profile ...
