... Since the IMF lies in the XY plane and B y is specified as positive in simulation Case 1, it can be inferred that the MSO and MSE coordinate systems align perfectly for this particular scenario. It is evident from the left column panels of Figure 1 that closed loops of the magnetic field lines form in the northern hemisphere and subsequently shift toward the southern hemisphere (refer to panels (1b) and (1d)), which is consistent with previous observations Dubinin et al., 2019;Zhang, Rong, et al., 2022). However, by assuming the same velocities and temperatures of different ion species, the previously-reported single fluid MHD approach fails to reproduce such a comparable shift (Li, G et al., 2023), suggesting that ion Solar wind velocity (km/s) Interplanetary magnetic field (nT) ...

... Based on both datasets of MGS and MAVEN, Gao et al. [72] developed a new Martian crustal field model which has the least fitting error than the previous models. To clarify the scientific objectives of the Lander of China's Mars mission, Li et al. [73] developed a regional high-resolution crustal field model based on both datasets of MGS and MAVEN, and inferred the magnetic field distribution on the Mars surface. Zhang et al. [74] statistically studied the 3-D magnetic field configuration around Mars, and found that the field structure in Martian magnetotail has an evident hemispheric asymmetry along the direction of solar wind electric field. ...

... This study aims to simulate the interaction between the solar wind and Mars using a multispecies MHD numerical model. A 110°spherical harmonic model developed by Gao et al. (2021) is included to describe the crustal fields. Instead of the Cartesian coordinate velocity components V x , V y , and V z , the spherical-coordinate velocity component V r is chosen to describe the vertical plasma motion in the Martian ionosphere, and both the components V θ , and V j are chosen to describe the horizontal plasma motion there. ...

... Previous crustal field models were established based on the MGS data at the altitude of about 400 km, and the MAVEN's data collected down to the altitude of 120 km provides an opportunity to establish a more accurate model. Based on both datasets of MGS and MAVEN, Gao et al. [72] developed a new Martian crustal field model which has the least fitting error than the previous models. To clarify the scientific objectives of the Lander of China's Mars mission, Li et al. [73] developed a regional high-resolution crustal field model based on both datasets of MGS and MAVEN, and inferred the magnetic field distribution on the Mars surface. ...
