Statistical characterizations of equatorial scintillation in the Asian region

Attention is given to the statistical aspect of equatorial scintillations in the Asian region, using the power spectra of prominent scientillation events collected over a 16-month period during the solar maximum years of sunspot cycle 21. A series of comparisons between values is undertaken in order to assess such ionospheric parameters as the height and thickness of the irregularity layers, rms fluctuations of total electron content, and the axial ratio of the irregularities. The results obtained suggest that equatorial ionospheric irregularities in the F region, with sub-km sizes in the evening hours after local sunset, are the main cause of the GHz scintillations observed. The spectra of the irregularities appear to be of the power law type, with spectral indices whose values are generally greater than 4.
