The Mars Science Laboratory (MSL) landed on Mars in Gale crater in 2012, and, since then, the rover has been almost continuously observing the meteorology within the crater using the Rover Environmental Monitoring Station (REMS; Gómez-Elvira et al., 2012). Among the regular observations by REMS have been surface pressure, UV radiation flux, air temperature, humidity, and ground temperature (measurements of wind speed and direction were constrained to moments when the wind was blowing onto the front of the rover after a second, complementary wind sensor was damaged upon landing). Additionally, MSL cameras provide atmospheric information that includes estimates of atmospheric dust loading and detection of dust devils and water ice clouds (Guzewich
