Comparison of CIMI Simulations and TWINS Observations on June 28 and 29, 2013 

Shekhar, Sapna; Perez, J; Davidson, K; Fok, M; 0000-0002-5619-9093; 0000-0002-2815-4998 (2022-10-27)
A moderate geomagnetic storm (Sym/H similar to-100 nT) during June 28 and 29, 2013 was studied using Comprehensive Inner Magnetosphere-Ionosphere (CIMI) simulations and results were compared with Two wide-angle Imaging ...

The Comprehensive Inner Magnetosphere-Ionosphere Model 

Fok, M; Buzulukova, N; Chen, S; Glocer, A; Nagai, T; Valek, P; Perez, J; 0000-0001-9500-866X; 0000-0001-9843-9094; 0000-0002-2318-8750 (2023-01-31)
Simulation studies of the Earth's radiation belts and ring current are very useful in understanding the acceleration, transport, and loss of energetic particles. Recently, the Comprehensive Ring Current Model (CRCM) and ...

Global images of trapped ring current ions during main phase of 17 March 2015 geomagnetic storm as observed by TWINS 

Perez, J; Goldstein, J; McComas, D; Valek, P; Fok, M; Hwang, Kyoung-Joo; 0000-0001-9500-866X; 0000-0002-2318-8750 (2023-01-26)
A unique view of the trapped particles in the inner magnetosphere provided by energetic neutral atom (ENA) imaging is used to observe the dynamics of the spatial structure and the pitch angle anisotropy on a global scale ...

Magnetotail-Inner Magnetosphere Transport Associated With Fast Flows Based on Combined Global-Hybrid and CIMI Simulation 

Lin, Y; Wang, X; Fok, M; Buzulukova, N; Perez, J; Cheng, L; Chen, L; 0000-0002-4768-189X; 0000-0002-5619-9093; 0000-0002-8127-2248 (2022-11-01)
Using the combined Auburn global hybrid simulation code in 3-D (ANGIE3D) and the Comprehensive Inner Magnetosphere-Ionosphere (CIMI) model, we investigate the self-consistent connection of fast flow injections from the ...
