Martian Dust Particle Size During the 2018 Planet-Encircling Dust Storm as Measured by the Curiosity Rover

[摘要] We present retrievals of dust particle effective radius during the 2018 planet-encircling dust storm from the Mars Science Laboratory Curiosity rover. Four independent observations with three of the rover's instruments were used for retrievals. We find dust particle radii exceeded 4 m and possibly 5 m during the height of the storm, which represent the largest dust particles yet seen in the martian atmosphere.
