Abstract

This entry contains Fortran, IDL and Python codes that have been used to simulate MHD waves in the Earth's inner magnetosphere in spherical coordinates. We have studied low latitude oscillations close to the Earth and on the ground using this formulation. The contents of this entry are released in conjunction with the publication of our study which appears in the Journal of Geophysical Research: Space Physics.

Description

The Fortran code solves the cold plasma MHD equations in spherical coordinates. Two input files are required to run the simulation, and they are provided here. We provide IDL and Python routines to process and analyze the output and to generate the figures that appear in the publication.
