Abstract : Results are presented of studies of ionospheric scintillation job obtained by monitoring of transmissions from NNSS satellites at Kiruna, Northern Sweden during a two year period from September 1984 to September 1987. Attention is concentrated in this report on phase scintillation morphology. Also presented are results of model studies of the geometrical influences in amplitude and phase scintillations at a high-latitude site aimed at interpreting the observations and understanding the nature of the ionospheric irregularities responsible for the scintillations. Also discussed are results of two coordinated studies of ionospheric irregularities using scintillation observations and data from Hf and VHF backscatter radar systems respectively. Keywords: Radio-wave scintillations, Ionospheric irregularities, and High-latitude ionosphere.
