How will the crustal magnetic field affect the tail reconnection process at Mars?

We use a fully coupled global MHD model with an embedded Particle in Cell (PIC) code to further understand the magnetic reconnection process on Mars and its consequences, especially how will the crustal magnetic field affect the tail reconnection process. This two-way coupled MHD-EPIC model has been applied to Mars and performed a detailed study for a tail reconnection event observed by MAVEN [Harada et al., 2015]. In this study, four more cases will be studied with the same solar wind condition but for different crustal field orientations. The subsolar longitude for the baseline case is at 73.1 east longitude. For the four cases, the subsolar longitude is set to 0, 90, 180 and 270 degrees east longitude, with the strong crustal field located in the nightside, dawn, dayside and dusk side, respectively. Detailed analysis of the model results will then be presented to show the relation between crustal field and tail reconnection process at Mars.
