D.T. (2018). Multispecies and multifluid MHD approaches for the study of ionospheric escape
at Mars. Journal of Geophysical Research: Space Physics, 123. https://doi.org/10.1029/2017JA025117
Research overview:
The paper presents a detailed comparison between the results provided by a multi-species
and a multi-fluid MHD models to study the escape of heavy ions from the Martian
ionosphere.
The research presented in the paper was conducted in 2017 at the Department of Climate
and Space Sciences and Engineering and the simulations were run at NASA's Pleiades
supercomputer.
Methods:
The three models involved (Mars Global Ionosphere Thermosphere Model, M-GITM, the multi-
species MHD, MS-MHD, and the multi-fluid MHD MF-MHD) were run until reaching steady
state on the Pleiades supercomputer. M-GITM was run for a month of simulation time, for
the period of time between July and August 2015. The MHD models were run for 50,000
iterations using the neutral densities from M-GITM as ion sources. The details of the
models can be found in Bougher et al. (2015) (M-GITM), Ma et al. (2004) (MS-MHD) and
Najib et al. (2011) (MF-MHD).
File inventory: there are two different sets of outputs for some of the models. The
original set is from the original paper submission, while the updated set corresponds
to some files produced during the review process. The updated set and original files
marked "NOT DEPRECATED" contain the files from which all the analysis and figures in
the published version of the paper were produced.
(UPDATED) The data files correspond to the following:
revised_shl_ful_5_n00050000_mfmhd_paper.out: MF-MHD output in binary format. Spherical D
shells between 2 and 6 Mars radii (RM) in steps of 1 RM.
revised_3d__ful_4_n00050000_msmhd_paper.out: MS-MHD output in binary format. Full domain D
in cartesian coordinates.

in cartesian coordinates.
revised_3d__ful_4_n00050000_mfmhd_paper_nocrustal.out: MF-MHD output in binary format. D
