He+ dominance in the plasmasphere during geomagnetically disturbed periods: 1. Observational results
Publikováno v:
Annales Geophysicae, Vol 20, Pp 461-470 (2002)
Observations made by the DMSP F10 satellite during the recovery phase from geomagnetic disturbances in June 1991 show regions of He+ dominance around 830 km altitude at 09:00 MLT. These regions are co-located with a trough in ionisation observe

The coupled thermosphere–ionosphere–plasmasphere (CTIP) model is a three–dimensional model that solves equations of continuity, momentum and energy balance to calculate ion and electron concentrations, temperatures and field–aligned velocitie

Geomagnetic field–line resonances may be identified via the use of cross–phase analysis of data from two closely spaced meridional ground–based magnetometer stations. It has been demonstrated that preprocessing of the data using a wavelet–bas

The upper atmosphere is an extremely dynamic system and is dependent on the sun’s influence on the earth. This influence results in complex physical and chemical processes, which, with the aid of mathematical models can be analysed. The Sheffield c

Cold plasma mass density profiles in the plasmasphere have been determined for the geomagnetically quiet day of 19th August 2000 using the cross-phase technique applied to ground-based magnetometer data from the SAMNET, IMAGE and BGS magnetometer arr

[1] Light ion concentration observations from the Arecibo incoherent scatter radar have shown regions of He+ layering in the topside ionosphere in the postmidnight hours. The He+ layering phenomenon has been observed during both solar maximum and sol
