We report phase-scintillation estimates in the high-latitude ionosphere inferred from high-resolution radio occultation (RO) measurements using CASSIOPE - GPS satellite radio links. For December 1, 2013, RO phase measurements from GPS SVN 50, we have computed phase-scintillation estimates (in distance units) ranging from about 1 cm to 18 cm. The RO phase measurements were concurrent with the occurrence of geomagnetic storms, substorms, and interplanetary magnetic field (IMF) southward conditions signifying the control of the plasma dynamics of the polar ionosphere by solar wind and magnetospheric drivers. Hence, the phase-scintillations were principally caused by plasma instabilities, which were driven by the storm and substorm conditions. The largest phasescintillation values most likely correspond to RO measurements carried out over turbulent regions in the auroral oval during moderate substorms (with Auroral Electrojet Index of ∼600 nT).
