STUDIES OF SPATIAL IRREGULARITIES IN THE IONOSPHERE AND THEIR VARIATIONS WITH TIME.
Abstract
A chronological account is given of participation in the program of a KC-135 aircraft at AFCRL equipped with an ionosonde. Results of a search for propagation of high frequency waves in magnetospheric ducts from the northern hemisphere to the southern hemisphere were negative. Development of techniques and equipment for study of travelling ionospheric distrubances by obliquepath ionograms was continued from the preceding contract. System synchronization is obtained by basing the frequencysweeps and pulsing on stable frequency standards at each location. Frequency sweeping is phased to transmissions from WWV, CHU, or NBA, and pulsing is phased to transmissions from Loran-C stations. Travelling ionospheric disturbances are discussed. The effect of gravity on magneto-acoustic waves in the ionosphere was studied theoretically. Moving irregularities were observed on an ionosonde at vertical incidence. These were reduced to true height and analyzed in terms of the theoretical findings. (Author)
