    Topography around Mons Rümker region, which is figured out with a white box. The black box indicates the candidate landing site of CE-5 proposed by reference [10], and this site is centered at (303.34ºE, 40.11ºN)
    Schematic of illumination condition
    Morning map of illumination over Mons Rümker at the lunar local time tm = 06:30:30: (a) Japan’s SELENE morning map of illumination; (b) our estimated relative intensity of illumination at the same time of Fig. 3(a)
    Surface temperature distribution with time over Mons Rümker plateau: (a) Time at UTC 2020-10-28T 11:30:00; (b) time at UTC 2020-10-29T 06:45:00; (c) time at UTC 2020-10-30T 06:45:00; (d) time at UTC 2020-11-02T 04:45:00; (e) time at UTC 2020-11-12T 02:45:00; (f) time at UTC 2020-11-12T 17:00:00
    Subsurface temperature distribution at the depth of 5 cm over Mons Rümker plateau: (a) Time at UTC 2020-10-28T 11:30:00; (b) time at UTC 2020-10-29T 06:45:00; (c) time at UTC 2020-10-30T 06:45:00; (d) time at UTC 2020-11-02T 04:45:00; (e) time at UTC 2020-11-12T 02:45:00; (f) time at UTC 2020-11-12T 17:00:00
    Temperature variation along the longitude direction shown in Fig.1: (a) Time at UTC 2020-10-28T 11:30:00; (b) time at UTC 2020-10-29T 06:45:00; (c) time at UTC 2020-10-30T 06:45:00; (d) time at UTC 2020-11-02T 04:45:00; (e) time at UTC 2020-11-12T 02:45:00; (f) time at UTC 2020-11-12T 17:00:00. The black carves in Fig. 6(d) represents the surface topography along the same blue line direction displayed in Fig. 1
    Subsurface temperature variations: (a) Variations for the point of CE-5 candidate landing site; (b) variations for the black star in Fig. 1
