Dynamics of ring current ions as obtained from IMAGE HENA and MENA ENA images
Perez, JD; Zhang, XX; Brandt, PCS; Mitchell, DG; Jahn, JM; Pollock, CJ (2020-06-18)
Ion distributions from three storms in the year 2000 have been obtained from HENA and MENA ENA images at 27-39 keV and 5-12 keV, respectively. The observed motion of the ring current is compared with calculations of expected ...
Global patterns of Joule heating in the high-latitude ionosphere
Zhang, XX; Wang, C.; Chen, T.; Wang, YL; Tan, A; Wu, TS; Germany, GA; Wang, W (2020-06-18)
[1] A compiled empirical global Joule heating (CEJH) model is described in this study. This model can be used to study Joule heating patterns, Joule heating power, potential drop, and polar potential size in the high-latitude ...
Trapped and precipitating protons in the inner magnetosphere as seen by IMAGE
Perez, JD; Zhang, XX; Brandt, PC; Mitchell, DG; Jahn, JM; Pollock, CJ; Mende, SB (2020-06-18)
[1] Images from the IMAGE satellite of precipitating protons (SU12/FUV) and trapped protons at 8.5 (MENA) and 33 keV (HENA) are compared during three periods: ( 1) 12 August 2000 from 1000 UT to 1145 UT just after the peak ...
