Time-evolution of lag thickness and ice sublimation rate of a Martian dirty ice deposit. a Modeled increase in lag thickness over time for different atmospheric humidities (solid vs. dashed lines) and ice deposit dust concentrations (black vs. gray lines) assuming an ice surface temperature of 210 K. The minor ticks on the x-axis give even increments from the base. The lag thickness in a is given by the buried ice sublimation rate calculated from Eq. 5 (b) integrated over time and multiplied by the dust concentration. This calculation assumed an initial debris thickness of 1 cm. The blue line in a gives the assumed debris thickness used to calculate the ablation rate in the simulation
