Global Ionospheric TEC Variability: Long‐Term Spectral–Wavelet Analysis and Geomagnetic Storm Event Case Studies

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract This study investigates global ionospheric variability using Global Total Electron Content (GTEC), defined as the spatial average of daily averaged Global Ionospheric Maps derived from the International GNSS Service. The analysis spans from 2010 to 2024, covering Solar Cycle 24 and the rising phase of Solar Cycle 25, and incorporates ...

Geomagnetic activity during the rising phase of solar cycle 24

Journal of Space Weather and Space Climate, 2013
As previous studies have shown, geomagnetic activity during the solar minimum following solar cycle 23 was at low levels unprecedented during the space era, and even since the beginning of the Kp index in 1932.

Polarization Measurements and Source Locations of Saturn Electrostatic Discharges During the Voyager Era

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract A Saturn Electrostatic Discharge or SED is an intense electromagnetic impulse induced by Saturn lightning, which escapes into space through the magnetoplasma of the ionosphere. Since previous SED polarizations from Voyager data are inconclusive, this polarization study is the first which properly considers the characteristics of the Voyager ...

Determination of the Far-Infrared Cosmic Background Using COBE/DIRBE and WHAM Data

, 2007
Determination of the cosmic infrared background (CIB) at far infrared wavelengths using COBE/DIRBE data is limited by the accuracy to which foreground interplanetary and Galactic dust emission can be modeled and subtracted. Previous determinations of the

Shock deceleration in interplanetary coronal mass ejections (ICMEs) beyond Mercury’s orbit until one AU

Journal of Space Weather and Space Climate, 2018
The CDPP propagation tool is used to propagate interplanetary coronal mass ejections (ICMEs) observed at Mercury by MESSENGER to various targets in the inner solar system (VEX, ACE, STEREO-A and B). The deceleration of ICME shock fronts between the orbit

FINE TIME STRUCTURE OF LIGHTNINGS ON SATURN

Radio Physics and Radio Astronomy, 2014
The results are reported of the very first study of Saturn lightning fine time structure with superfine time resolution (within hundreds to units of nanoseconds). It is ascertained that the lightning time structure has two intrinsic scales: from hundreds/

Connecting speeds, directions and arrival times of 22 coronal mass ejections from the Sun to 1 AU

, 2014
Forecasting the in situ properties of coronal mass ejections (CMEs) from remote images is expected to strongly enhance predictions of space weather, and is of general interest for studying the interaction of CMEs with planetary environments. We study the
