Scintillation and In-situ Irregularity Parameters in the Auroral Oval and Polar Cap

The orbiting HiLat satellite launched by the Defense Nuclear Agency in 1983 offered a unique opportunity for studying ionospheric scintillation parameters in relation to in-situ irregularity parameters. An earlier report (AFGL-TR-87-0245) summarized our findings during the sunspot minimum period of...

Description
Summary:The orbiting HiLat satellite launched by the Defense Nuclear Agency in 1983 offered a unique opportunity for studying ionospheric scintillation parameters in relation to in-situ irregularity parameters. An earlier report (AFGL-TR-87-0245) summarized our findings during the sunspot minimum period of 1983-1985 for data obtained at Tromso, Norway. In this report, we extend our study to the sunspot maximum period of 1988-1989. For completeness, we augment the HiLat scintillation data by phase and amplitude scintillation morphology obtained with the help of the quasi-geostationary polar beacon satellites at Tromso during the period 1988 to 1990. To contrast these two distinct high latitude regions, we provide scintillation morphology using polar beacon satellites from Thule, Greenland for the period 1987 to 1990. Some new findings emerge on the UT and seasonal variation of high latitude scintillation as a result of this study.
