| Zusammenfassung |
| Successful empirical modeling of the topside ionosphere relies on the
availability of good quality measured data. The Alouette, ISIS and
Intercosmos-19 satellite missions provided large amounts of topside sounder
data, but with limited coverage of relevant geophysical conditions (e.g.,
geographic location, diurnal, seasonal and solar activity) by each individual
mission. Recently, methods for inferring the electron density distribution in
the topside ionosphere from Global Positioning System (GPS)-based total
electron content (TEC) measurements have been developed. This study is
focused on the modeling efforts in South Africa and presents the
implementation of a technique for reconstructing the topside ionospheric
electron density (Ne) using a combination of GPS-TEC and ionosonde
measurements and empirically obtained Upper Transition Height (UTH). The technique
produces reasonable profiles as determined by the global models already in
operation. With the added advantage that the constructed profiles are tied to
reliable measured GPS-TEC and the empirically determined upper transition
height, the technique offers a higher level of confidence in the resulting
Ne profiles. |
