Pressure profiles along the Sun-Mars line on the dayside with the same solar wind condition as in Case 1 of Ma et al. (2004) for panel a. The solid black, red, green, cyan, and blue lines represent the solar wind dynamic pressure P_d (SW), the solar wind plasma thermal pressure P_th(SW), the ionosphere thermal pressure P_th(ion), the magnetic pressure P_B, and the totalpressure P(SW), respectively.The small circles indicate the positions of the radial grid points, and the vertical dashed line represents the identified location of the subsolar standoff point of the Martian MPB. Panel b: similar pressure profiles for n = 1 (solid lines) and 9 (dashed lines) cm⁻³ when P_d = 1 nPa. The black, red, and cyan lines stand for P_d(SW), P_th (SW), and P_B, respectively. The vertical blue lines represent the corresponding identified locations of the subsolar standoff point of the Martian MPB. Panels c and d: corresponding conditions of the solar wind electron temperature (T_e (K)) and thesolar wind number density (n (cm⁻³)) for panel b along the Sun-Mars line.
