Meteorological environmental comparisons at multiple Martian landing sites based on the Mars Climate Database (MCD) and in situ observations. (a) Mean wind speed and gravitational dust deposition rate at the Zhurong landing site. Data are obtained from the MCD and the Zhurong Mars Climate Station (MCS). The MCD outputs represent the envelope of diurnal maximum and minimum values within a Martian sol. (b) Atmospheric optical depth derived from the MCD at the Zhurong landing site. (c) Near-surface wind speeds at different Martian rover landing sites. (d) Near-surface atmospheric temperatures at different Martian rover landing sites.
