Measuring Electrodynamics of the Ionosphere by Digital Ionosondes and Other Techniques
Abstract
Ionospheric sounding in the equatorial and high latitude ionosphere and the development of new analysis techniques shows new ways for ionospheric diagnostics comparison of Digisonde ionograms and drift measurements with optical all sky images provides an explanation of the equatorial anomaly spread F signatures on ionograms, and their relation to satellite scintillation effects. For the auroral and polar cap region the Generalized Digisonde Drift Analysis (GDDA) program was developed to increase drift velocity fields. This facilitated the monitoring of polar patches. A new ARTIST4 system was developed for the AF Digisondes and the DISS system to strengthen the quality of the data and the station networking. All output data are now in the SAO 4.2 format. ARTIST4 now calculates an estimated topside profile with a scale height derived from the shape of the bottomside profile. Concept and breadboard designs of a topside sounder were developed and tested at the Millstone Hill digisonde site. These tests showed successful implementation of pulse and chirp waveforms for a topside advances sounder (TOPAS).
