Observations and numerical simulations of electrified, medium-scale traveling ionospheric disturbances (MSTIDs) in the nighttime, mid-latitude ionosphere
… medium-scale traveling ionospheric disturbances (MSTIDs). This will be accomplished primarily through an observational study and with the aid of numerical simulations. MSTIDs are instabilities in the ionosphere characterized by vertical displacements in electron density with wavefronts at an angle …

Medium Scale Travelling Ionospheric Disturbances sensed with GNSS TEC and SuperDARN
Medium Scale Travelling Ionospheric Disturbances (MSTIDs) are quasi-wavelike structures in ionospheric density that can be sensed using Global Navigational Satellite Service (GNSS) Total Electron Content (TEC) techniques and coherent scatter radars such as the Super Dual Auroral Radar Network …

Growth rate simulations of instability mechanisms at low and mid-latitudes for explaining equatorial spread F
… traveling ionospheric disturbances (MSTIDs) coupling into equatorial regions and initiating ESF there. It is proposed that the polarization electric fields of MSTIDs provide the seed mechanism to initiate ESF for post--midnight, solar minimum times. To begin, background information on …

Techniques for automated classification of nighttime ionospheric images
… of the images collected contain neither EPBs nor MSTIDs, or are contaminated by other light sources or clouds. In order to identify the images of interest, discriminative classification models are considered for determining the relationship between measured image features and labels for a sequence …

Ionospheric Disturbances: Midlatitude Pi2 Magnetospheric ULF Pulsations and Medium Scale Traveling Ionospheric Disturbances
… medium scale traveling ionospheric disturbances (MSTIDs) at both midlatitudes and high latitudes. Consistent with prior studies, the climatological MSTID population in both latitudinal regions was found to peak in the fall and winter and have a dominant equatorward propagation direction. Prior …

Radio and Optical Techniques for Locating Equatorial Plasma Irregularities
… mesoscale traveling ionospheric disturbances (MSTIDs) seed post-midnight equatorial plasma depletions during geomagnetic quiet periods at solar minimum.
