    Identifying Equatorial Ionospheric Irregularities using In Situ Ion Drifts 

    Stoneback, Russell A.; Heelis, Roderick A. (Copernicus Gesellschaft Mbh, 2014-04-15)
    Previous climatological investigations of ionospheric irregularity occurrence in the equatorial ionosphere have utilized in situ measurements of plasma density to identify the presence of an irregularity. Here we use the ...

    The Ion/Electron Temperature Characteristics of Polar Cap Classical and Hot Patches and their Influence on Ion Upflow 

    Ma, Y. -Z; Zhang, Q. -H; Xing, Z. -Y; Heelis, Roderick A.; Oksavik, K.; Wang, Y.
    The term of “polar cap hot patch” is a newly identified high-density plasma irregularity at high latitudes, which is associated with high electron temperature and particle precipitation, while a classical polar cap patch ...

    The Plasma Environment Associated with Equatorial Ionospheric Irregularities 

    Smith, Jonathon M.; Heelis, Roderick A.
    We examine the density structure of equatorial depletions referred to here as equatorial plasma bubbles (EPBs). Data recorded by the Ion Velocity Meter as part of the Coupled Ion Neutral Dynamics Investigation (CINDI) ...

    Plasma Dynamics Associated with Equatorial Ionospheric Irregularities 

    Smith, Jonathon Matthew; Heelis, Roderick A.
    The Communication/Navigation Outage Forecasting System satellite was operational from 2008, a period of deep solar minimum, to 2015, a period of moderate solar conditions. The behavior of the vertical plasma drift and the ...

    Duskside Enhancement of Equatorial Zonal Electric Field Response to Convection Electric Fields During the St. Patrick's Day Storm on 17 March 2015 

    Tulasi Ram, S.; Yokoyama, T.; Otsuka, Y.; Shiokawa, K.; Sripathi, S.; Veenadhari, B.; Heelis, Roderick A.; Ajith, K. K.; Gowtam, V. S.; Gurubaran, S.; Supnithi, P.; Le Huy, M. (Blackwell Publishing Ltd, 2016-01-11)
    The equatorial zonal electric field responses to prompt penetration of eastward convection electric fields (PPEF) were compared at closely spaced longitudinal intervals at dusk to premidnight sectors during the intense ...

    Temporal Characteristic of the Mesoscale Plasma Flow Perturbations in the High-Latitude Ionosphere 

    Chen, Yun-Ju; Heelis, Roderick A. (Amer Geophysical Union, 2019-01-03)
    Spatial and temporal characteristics of flow perturbations in the high-latitude ionosphere are important considerations for energy deposition from the magnetosphere. In this study, we examine the temporal characteristics ...
