Seasonal dependence of MSTIDs obtained from 630.0 nm airglow imaging at Arecibo

Geophysical Research Letters, 2010
All‐sky imaging data of 630.0 nm airglow emissions are used to study the seasonal and solar activity dependence of medium‐scale traveling ionospheric disturbances (MSTIDs) over Arecibo, Puerto Rico (18.3° N, 66.7° W, 28° N mag lat). MSTIDs are typical F‐region signatures at midlatitudes, yet limited statistical results in the American sector hindered ...

Comparison of electron densities and temperatures on satellite in situ measurements and ground remote ob servations

, 2019
© 2019 IEEE. To determine the degree of connectivity of the electron density disturbance of the MSTID type below and above the F layer peak, a comparison data of the ionosonde and the low-orbit constellation of the Swarm satellites was made. It was found

Climatology of the spread F over Roquetes, Spain: Impact of the medium scale traveling ionospheric disturbances

Journal of Space Weather and Space Climate
Understanding the long-term variability of nighttime Spread F (SF) and its drivers is crucial for improving the knowledge of ionospheric disturbances, which impact radio communication, GNSS positioning, and space weather forecasting.

Multi-instrument analysis of medium-scale travelling ionospheric disturbances generated by an intense tropospheric jet-front system with severe convection in Europe in August 2023

Journal of Space Weather and Space Climate
Tropospheric jet-front systems and intense convection are known to be potential sources of atmospheric gravity waves (AGWs), which can propagate upward.

MSTID forecasting software codes delivered by the T-FORS project

This report provides a description of the codes that estimate the climatological pattern of MSTIDs, developed in the T-FORS project. The MSTID climatology is based on the detrended TEC data and can be used as a long-term forecasting tool. The validation confirms the expected diurnal and seasonal variability of the physical phenomenon.
