On the Origins of Mercury's Sodium Exospheric Cold Poles Enhancement: A Multiscale Exosphere Global Model

Na_Column_Density_Surface_*1ML* or*Many_ML*.zip : Contains the Column Density Maps at different True Anomaly Angle. The first number in each file's name represents the year (1,2,...) and the last number in each file's name is the TAA. Each file is a contains 24 columns and 40 rows (respectively for the latitudes and longitudes). (Figure 1 & 3) D_SubsolList_Sub.dat : Contains a list with two columns. The first is the TAA and the second is the rotation between the MSO referential and the East Longitude one. density_TAA_TAA_timsteps.nc : NetCDF files containing the instaneous state of the exosphere at TAA stated in the file name. Contains density, velocity, grids, ... (Figure 2, 4, 5, 6) sub_density_TAA_TAA_timsteps.nc : NetCDF files containing the instaneous state of the subsurface at TAA stated in the file name. Contains density, velocity, grids, ... (Figure 2, 4) MESSENGER data in Figure 6 are available on PDS.Na_Column_Density_Surface_*1ML*或*Many_ML*.zip：包含不同真近点角(True Anomaly Angle, TAA)下的柱密度图。每个文件名的首位数字代表年份（1、2……），末位数字为真近点角数值。每个文件包含24列与40行数据，分别对应纬度与经度。（对应图1与图3） D_SubsolList_Sub.dat：包含两列数据的列表，第一列为真近点角，第二列为磁层太阳轨道参考系(MSO referential)与东经坐标系之间的旋转角。 density_TAA_TAA_timsteps.nc：NetCDF格式文件，包含文件名中指定的真近点角下的外逸层瞬时状态数据，包含密度、速度、网格等信息。（对应图2、4、5、6） sub_density_TAA_TAA_timsteps.nc：NetCDF格式文件，包含文件名中指定的真近点角下的次表层瞬时状态数据，包含密度、速度、网格等信息。（对应图2、4） 图6中的信使号(MESSENGER)数据可在行星数据系统(Planetary Data System, PDS)获取。
