Daytime Equatorial Spread F‐Like Irregularities Detected by HF Doppler Receiver and Digisonde

Space Weather, 2021
Daytime equatorial spread F (ESF) is not as common as nighttime ESF due to the presence of a highly conducting E‐layer during the daytime which counteracts the development of F‐layer plasma irregularities.

Interaction between Equatorial Plasma Bubbles and a Medium-Scale Traveling Ionospheric Disturbance, observed by OI 630 nm airglow imaging at Bom Jesus de Lapa, Brazil

Earth and Planetary Physics, 2021
OI 630.0 nm airglow observations, from a new observatory at Bom Jesus de Lapa, were used to study the interaction between EPBs (Equatorial Plasma Bubbles) and the MSTID (Medium-Scale Traveling Ionospheric Disturbance) over the Northeast region in Brazil.

Traveling wave packets of total electron content disturbances as deduced from global GPS network data

, 2002
We identified a new class of mid-latitude medium-scale traveling ionospheric disturbances (MS TIDs), viz. traveling wave packets (TWPs) of total electron content (TEC) disturbances.

Medium-scale traveling ionospheric disturbances created by primary gravity waves generated by a winter storm

Journal of Space Weather and Space Climate
This study explores the meteorological source and vertical propagation of gravity waves (GWs) that drive daytime traveling ionospheric disturbances (TIDs), using the specified dynamics version of the SD-WACCM-X (Whole Atmosphere Community Climate Model ...

Spectral investigation of traveling ionospheric disturbances: IONOLAB-FFT

Geodesy and Geodynamics, 2017
Ionosphere is an important layer of atmosphere which is under constant forcing from both below due to gravitational, geomagnetic and seismic activities, and above due to solar wind and galactic radiation. Spatio-temporal variability of ionosphere is made up of two major components that can be listed as spatio-temporal trends and secondary variabilities

Detecting ionospheric TEC perturbations caused by natural hazards using a global network of GPS receivers: The Tohoku case study [PDF]

, 2012
Recent advances in GPS data processing have demonstrated that ground-based GPS receivers are capable of detecting ionospheric TEC perturbations caused by surface-generated Rayleigh, acoustic and gravity waves.

Ionospheric Disturbances Triggered by the Mw7.6 Earthquake off the Coast of El Salvador on 13 January 2001

Terrestrial, Atmospheric and Oceanic Sciences, 2006
A network of five ground-based receivers of the global positioning sys- tem (GPS) was use to detect seismo-ionospheric disturbances in the total elec- tron content (TEC) triggered by the 13 January 2001 El Salvador Mw 7.6 earthquake.

Rapid‐run ionosonde observations of traveling ionospheric disturbances in the auroral ionosphere [PDF]

Journal of Geophysical Research: Space Physics, 2013
AbstractSince 2007, the Sodankylä Geophysical Observatory routinely performs vertical ionosphere soundings once per minute, using a frequency‐modulated continuous‐wave chirp at the rate of 500 kHz/s from 500 kHz to 16 MHz. We used these data to study traveling ionospheric disturbances (TIDs) during 10–16 local time.
