    Ionosphere-Thermosphere (IT) Response to Solar Wind Forcing During Magnetic Storms 

    Huang, Cheryl Yu-Ying; Huang, Yanshi; Su, Yi-Jiun; Sutton, Eric K.; Hairston, Marc Rotan; Coley, William Robin (EDP Sciences S A, 2016-01-25)
    During magnetic storms, there is a strong response in the ionosphere and thermosphere which occurs at polar latitudes. Energy input in the form of Poynting flux and energetic particle precipitation, and energy output in ...

    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 ...

    Radar and Satellite Investigations of Equatorial Evening Vertical Drifts and Spread F 

    Smith, J. M.; Rodrigues, Fabiano S.; de Paula, E. R. (Copernicus Gesellschaft Mbh, 2015-11-11)
    We analyzed pre-midnight equatorial F region observations made by the 30 MHz coherent backscatter radar of Sao Luis, Brazil between August 2010 and February 2012. These measurements were processed, and used to create monthly ...

    Storm-Time Meridional Flows: A Comparison of CINDI Observations and Model Results 

    Hairston, Marc R.; Maruyama, N.; Coley, William R.; Stoneback, Russell A. (Copernicus Gmbh, 2014-06-17)
    During a large geomagnetic storm, the electric field from the polar ionosphere can expand far enough to affect the mid-latitude and equatorial electric fields. These changes in the equatorial zonal electric field, called ...

    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) ...

    Testing Nowcasts of the Ionospheric Convection from the Expanding and Contracting Polar Cap Model 

    Walach, M. -T; Milan, S. E.; Yeoman, T. K.; Hubert, B. A.; Hairston, Marc R. (Amer Geophysical Union, 2017-04-20)
    The expanding/contracting polar cap (ECPC) model, or the time-dependent Dungey cycle, provides a theoretical framework for understanding solar wind-magnetosphere-ionosphere coupling. The ECPC describes the relationship ...

    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 ...

    Observations of the Generation of Eastward Equatorial Electric Fields near Dawn 

    Kelley, M. C.; Rodrigues, Fabiano S.; Pfaff, R. F.; Klenzing, J. (Copernicus Gesellschaft Mbh, 2014-09-19)
    We report and discuss interesting observations of the variability of electric fields and ionospheric densities near sunrise in the equatorial ionosphere made by instruments onboard the Communications/Navigation Outage ...
