Dominant role of the asymmetric ring current in producing the stormtime
- M. Liemohn, J. Kozyra, +4 authors T. Cayton
- Physics
- 1 June 2001
Three storms are examined to determine the contribution to the Dst* index from the symmetric and asymmetric (partial) components of the ring current. The storms (September 24–25, 1998, October 18–19,… Expand
Analysis of early phase ring current recovery mechanisms during geomagnetic storms
- M. Liemohn, J. Kozyra, V. Jordanova, G. Khazanov, M. Thomsen, T. Cayton
- Physics
- 15 September 1999
A time-dependent kinetic model is used to investigate the relative importance of various mechanisms in the early phase decay rate of the ring current. It is found that, for both the solar maximum… Expand
Geomagnetic storms driven by ICME- and CIR-dominated solar wind
- M. Denton, M. Denton, +7 authors M. Liemohn
- Physics
- 1 July 2006
The interaction of the solar wind and the Earth's magnetosphere is complex and the phenomenology of the interaction is very different for solar wind dominated by interplanetary coronal mass ejections… Expand
Bulk plasma properties at geosynchronous orbit.
- M. Denton, M. Thomsen, H. Korth, S. Lynch, J. Zhang, M. Liemohn
- Physics
- 1 July 2005
We present a comprehensive study of plasma properties at geosynchronous orbit for electron and ion energies between ∼1 eV and ∼45 keV, between 1990 and 2001. The variations of temperature and density… Expand
How Hospitable Are Space Weather Affected Habitable Zones? The Role of Ion Escape
- V. Airapetian, A. Glocer, +4 authors M. Liemohn
- Physics
- 6 February 2017
Atmospheres of exoplanets in the habitable zones around active young G-K-M stars are subject to extreme X-ray and EUV (XUV) fluxes from their host stars that can initiate atmospheric erosion.… Expand
A statistical study of the geoeffectiveness of magnetic clouds during high solar activity years
- Jichun Zhang, M. Liemohn, J. Kozyra, B. Lynch, T. Zurbuchen
- Environmental Science
- 1 December 2003
[1] Using the Dst value corrected for the effects of magnetopause currents (Dst*) and solar wind magnetic field and plasma data from 1 January 1998 to 30 April 2002, during elevated solar conditions,… Expand
Multistep Dst development and ring current composition changes during the 4–6 June 1991 magnetic storm
- J. Kozyra, M. Liemohn, +6 authors W. Gonzalez
- Physics
- 1 August 2002
[1] The 4–6 June 1991 magnetic storm, which occurred during solar maximum conditions, is analyzed to investigate two observed features of magnetic storms that are not completely understood: (1) the… Expand
Hot Carbon Densities in the Exosphere of Mars
- A. Nagy, M. Liemohn, J. Fox
- 2001
Theoretical results of hot carbon densities in the exosphere of Mars are presented. The calculation is a two-step process: First a two-stream transport code is used to solve for the distribution… Expand
Origin and Evolution of Deep Plasmaspheric Notches
- D. Gallagher, M. Adrian, M. Liemohn
- Geology, Physics
- 1 December 2004
[1] Deep plasmaspheric notches can extend over more than 2 RE in radial distance and 3 hours MLT in the magnetic equatorial plane, as observed by the extreme ultraviolet (EUV) imager on the IMAGE… Expand
A statistical comparison of solar wind sources of moderate and intense geomagnetic storms at solar minimum and maximum
- Jichun Zhang, M. Liemohn, J. Kozyra, M. Thomsen, H. Elliott, J. Weygand
- Environmental Science
- 2006
[1] Superposed epoch analyses of 549 storms are performed to make a comparison of solar wind features of geomagnetic storm events at solar minimum (July 1974 to June 1977; July 1984 to June 1987;… Expand
