    • Effects of different geomagnetic storm drivers on the ring current: CRCM results 

      Cramer, W. Douglas; Turner, Niescja E.; Fok, M.C.; Buzulukova, N. Yu (2013-03)
      The storm-time magnetic disturbance at the Earth’s equator, as commonly measured by the Dst index, is induced by currents in the near-Earth magnetosphere. The ring current is generally considered the most important ...
    • Florida Energy Assurance Plan 

      Turner, Niescja E.; Murtagh, William J.; Guthrie, Kevin; Nykyri, Katariina; Radasky, William A.; Senkowicz, Eric (2012-08-29)
      This spring, Florida held the nations first statewide emergency preparedness training and exercises geared specifically to the aftermath of severe geomagnetic events. Funded by the State of Florida Division of Emergency ...
    • The horizontal electric field induced by a lightning return stroke 

      Meredith, Scott L.; Earles, Susan K.; Turner, Niescja E. (2010)
      Problem statement: Develop a new formula which describes the horizontal electric field induced by a lightning return stroke in contact with an imperfect conductive surface. Approach: A new method for describing the horizontal ...

    • A new method to describe image theory for an imperfect conductor 

      Meredith, Scott L.; Earles, Susan K.; Turner, Niescja E. (2010)
      Problem statement: Modify the equations associated with image theory in order to account for perfect and imperfect conductors. Approach: A novel approach for describing the application of image theory for an imperfect ...
    • Timing of substorm related auroral oscillations 

      Martin, P.; Turner, Niescja E.; Wanliss, James A. (2009-05-29)
      Previous studies have shown that auroral luminosity oscillations are often associated with substorms. Here we examine photometer data for the magnetospheric substorm on April 1, 2000 (expansive phase onset at 0525 UT) to ...
