Estimation and correction of scintillation effects on spaceborne P-band SAR images [PDF]

, 2012
A correction method for distortions induced by ionospheric scintillation effects on P-band quad-pol synthetic aperture radar (SAR) data acquired in polar and high latitude regions is presented.

Broadband meter‐wavelength observations of ionospheric scintillation [PDF]

Journal of Geophysical Research: Space Physics, 2014
Abstract Intensity scintillations of cosmic radio sources are used to study astrophysical plasmas like the ionosphere, the solar wind, and the interstellar medium. Normally, these observations are relatively narrow band.

SEPARATING NIGHTSIDE INTERPLANETARY AND IONOSPHERIC SCINTILLATION WITH LOFAR [PDF]

The Astrophysical Journal Letters, 2016
ABSTRACT Observation of interplanetary scintillation (IPS) beyond Earth-orbit can be challenging due to the necessity to use low radio frequencies at which scintillation due to the ionosphere could confuse the interplanetary contribution. A recent paper by Kaplan et al.

GPS scintillations and total electron content climatology in the southern low, middle and high latitude regions

Annals of Geophysics, 2013
In recent years, several groups have installed high-frequency sampling receivers in the southern middle and high latitude regions, to monitor ionospheric scintillations and the total electron content (TEC) changes.

Impacts of Mid‐Latitude Ionospheric Dynamics on RF Applications During the November 2025 Superstorm Event

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract This study demonstrates the intriguing and complex interplay among auroral precipitation, enhanced TEC, density irregularities, and amplitude scintillations observed during the November 2025 superstorm. For the first time, we present observations of strong amplitude scintillation across continental United States (CONUS)—nearly from coast to ...
