Anomalous attenuation of extraordinary waves in the ionosphere heating experiments

, 2001
Multiple scattering of radio waves by artificial random irregularities HF-induced in the ionosphere F region may cause significant attenuation of both ordinary and extraordinary waves together with common anomalous absorption of ordinary waves due to ...

Climatology of Equatorial Plasma Bubbles: Role of Gravity Wave Seeding and Ionospheric Preconditioning

Space Weather, Volume 24, Issue 3, March 2026.
Abstract This study investigates the linkage between mesopause gravity waves and equatorial plasma bubbles (EPBs) from 2012 to 2015 using the collocated nightglow measurements, O2 (762 nm) and OI (630 nm), observed by the Visible and near‐Infrared Spectral Imager onboard the International Space Station under the Ionosphere, Mesosphere, upper Atmosphere,

PPP‐RTK Atmospheric Correction Generation and Service Applicability: A Case Study During Typhoon Saola and Moderate Geomagnetic Disturbances in Hong Kong

Space Weather, Volume 24, Issue 3, March 2026.
Abstract Complex space weather, such as typhoons and solar activity, can cause heavy rainfall and ionospheric disturbances, affecting the quality of Global Navigation Satellite System (GNSS) signals. Among GNSS positioning techniques, Precise Point Positioning Real‐time Kinematic (PPP‐RTK) uses atmospheric corrections and bias products to achieve fast ...

Validation of Ionospheric Models at Mid‐ and High‐Latitudes: Climatological Performance of WACCM‐X (SD) and TIE‐GCM in foF2

Space Weather, Volume 24, Issue 3, March 2026.
Abstract Modeling the high‐latitude ionosphere‐thermosphere system is imperative to understanding the impacts of space weather on modern technology, such as communications and navigation systems. At low‐ and mid‐latitudes, physics‐based and empirical models are well‐developed and capture the variability of the ionosphere to a good degree of accuracy ...

Plasma diagnostic experiments on board of the Brazilian scientific microsatellite SACI-1 [PDF]

Geofísica Internacional, 2000
A set of three plasma diagnostic experiments, known as PLASMEX, are planned to investigate ionospheric plasma bubbles in the ionospheric region. We propose to measure the density, temperature and spectral distribution of irregularities of plasma using (1)

Spatial frequencies associated with the latitudinal structures of ionospheric currents seen by CHAMP satellite

, 2015
The CHAMP magnetic field variations during international quiet days of low solar activity period 2008-2009 are investigated. The present paper reports the existence of frequency-peaks < 20 mHz in the compressional component of the magnetic field in ...

Wave propagation and earth satellite radio emission studies [PDF]

Radio propagation studies of the ionosphere using satellite radio beacons are described. The ionosphere is known as a dispersive, inhomogeneous, irregular and sometimes even nonlinear medium. After traversing through the ionosphere the radio signal bears
